  • 功能

    This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen. Isoform 2 is involved in the regulation of the contraction/relaxation cycle.

  • 组织特异性

    Isoform 1 is widely expressed in smooth muscle and nonmuscle tissues such as in adult skin epidermis, with highest expression in liver, pancreas and lung, and intermediate expression in brain, kidney and placenta. Also expressed at lower levels in heart and skeletal muscle. Isoforms 2 and 3 are highly expressed in the heart and slow twitch skeletal muscle. Expression of isoform 3 is predominantly restricted to cardiomyocytes and in close proximity to the sarcolemma. Both isoforms are mildly expressed in lung, kidney, liver, pancreas and placenta. Expression of isoform 3 is amplified during monocytic differentiation and also observed in the fetal heart.

  • 疾病相关

    Defects in ATP2A2 are a cause of acrokeratosis verruciformis (AKV) [MIM:101900]; also known as Hopf disease. AKV is a localized disorder of keratinization, which is inherited as an autosomal dominant trait. Its onset is early in life with multiple flat-topped, flesh-colored papules on the hands and feet, punctate keratoses on the palms and soles, with varying degrees of nail involvement. The histopathology shows a distinctive pattern of epidermal features with hyperkeratosis, hypergranulosis, and acanthosis together with papillomatosis. These changes are frequently associated with circumscribed elevations of the epidermis that are said to resemble church spires. There are no features of dyskeratosis or acantholysis, the typical findings in lesions of Darier disease.
    Defects in ATP2A2 are the cause of Darier disease (DD) [MIM:124200]; also known as Darier-White disease (DAR). DD is an autosomal dominantly inherited skin disorder characterized by loss of adhesion between epidermal cells (acantholysis) and abnormal keratinization. Patients with mild disease may have no more than a few scattered keratotic papules or subtle nail changes, whereas those with severe disease are handicapped by widespread malodorous keratotic plaques. In a few families, neuropsychiatric abnormalities such as mild mental retardation, schizophrenia, bipolar disorder and epilepsy have been reported. Stress, UV exposure, heat, sweat, friction, and oral contraception exacerbate disease symptoms. Prevalence has been estimated at 1 in 50000. Clinical variants of DD include hypertrophic, vesicobullous, hypopigmented, cornifying, zosteriform or linear, acute and comedonal subtypes. Comedonal Darier disease (CDD) is characterized by the coexistence of acne-like comedonal lesions with typical Darier hyperkeratotic papules on light-exposed areas. At histopathologic level, CDD differs from classic DD in the prominent follicular involvement and the presence of greatly elongated dermal villi.

    Question

    Thank you so much about info of your antibodies, it helped me a lot. I did the scanning for sequence alignments across different species and it seems that ab77289 sequence is quite conserved. In danio there was difference just between 1-2 amino acids, same for tilapia (those are the only two fishes where SERCA2 has been sequenced or sequence has been published). And comparison to frogs, lizards, birds and mammals was even more compatible. And what was nice to notice, in invertebrates the difference was not too bad either. So I think if any of your antibodies are going to work it is the ab77289. Obviously, as you said, there is no certainty that it will work with salmonids but at least I can test it. Thank you Kate! Cheers,

    Answer

    Thank you for your enquiry. I am sorry to hear that you have been having difficulties with this antibody. Thank you for taking the time to complete our technical questionnaire. Our mouse monoclonal [IID8] to SERCA2 ATPase (ab2817) has been applied in many publications and we have received relatively few complaints about it. At this stage I would like to make the following recommendations: We recommend that the antibody is applied by western blot at a dilution of 1/2500. Therefore in order to improve the specificity of the antibody I would like to recommend that you reduce the dilution that you have been applying this antibody. This often serves to reduce the intensity of extraneous bands. In order to further reduce non specific bands I would like to recommend that you also reduce the mass of protein that you have been loading from 100ug to ~30ug of extract. This should be more than sufficient to detect this protein. I would also like to suggest that you change the blocking agent from milk to 3% BSA and supplement your antibody incubations with this agent. We often find that this serves to reduce background and/or extraneous bands that may be present. Please get back in touch with me should this not serve to improve your results.

    Question

    I need a SERCA2 antibody (which recognizes SERCA2B) for Xenopus laevis. None of your epitopes are available so I cannot evaluate your selection. I have attatched to this e-mail the probable amino acid sequence for this protein in Xenopus and am interested to hear your thoughts on potential antibody choices.

    Read More
    Answer

    Thank you for your enquiry. Regarding ab2817 and ab2861: These monoclonal antibodies have not been epitope mapped, therefore the epitope could be anywhere along the full length of the protein. I did an alignment of Human SERCA2 with the Xenopus SERCA2 sequence you attached to your email, and they are 92% homologous. I am not sure if this information helps you in your decision, but I thought I would let you know. I am still looking into ab3625 to see if I can uncover more information about the peptide that was used to produce this antibody. Once I find anything more, I will let you know. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

    Question

    DESCRIPTION OF THE PROBLEM I am not getting any bands. For the NCX and SERCA antibodies I am getting a dark smear corresponding to the stacking gel that is not present with the RyR or Alpha2, or with ab3516 and 2865 (these two are working well). SAMPLE The protein is from sheep. I have a total protein prep that is working well for phospholamban, calsequestrin, phosph-ERK and ERK2 detection. I also have a membrane protein prep that I'm not 100% confident with- so far I haven't detected any specific bands by blotting. However, bands from this prep are visible when I do a Coomassie stain. PRIMARY ANTIBODY I am using your primaries at the recommended dilution. I incubated the primaries overnight at 4C. I wash once for 20 minutes with TBST, then rinse again briefly with TBST. DETECTION METHOD I am using Pierce's SuperSignal. I have left the blots to expose for up to 15 minutes, or until the background made it impossible to see anything. Typically I have low background. POSITIVE AND NEGATIVE CONTROLS USED None. ANTIBODY STORAGE CONDITIONS Also antibodies 6495, 2868 and 2864. Antibodies aliquoted and stored at -20. NCX antibody reconstituted in 200ul PBS, aliquoted and stored at -20. SAMPLE PREPARATION Prior to loading on a gel the proteins are mixed with Laemmli buffer. I've tried increasing the ratio of the buffer to the sample. AMOUNT OF PROTEIN LOADED I've tried these with 20ug of protein up to more than a mg. ELECTROPHORESIS/GEL CONDITIONS Standard SDS-PAGE. I've tried running a 4% stacking gel & 12% resolving gel, also a 3% stacking gel and 5% resolving gel. I am now using a small gel system, but I have tried a larger format in the past. TRANSFER AND BLOCKING CONDITIONS The transfer buffer is Tris based and has glycine. I have tried transfering for 30min and 60min on Bio-Rad's Transblot SD. I block with 5% nonfat milk in TBST. SECONDARY ANTIBODY I am using Amersham ECL anti-rabbit (NA934) and anti-mouse (NA931) secondaries at 1:4000, this works extremely well for other primaries in this lab. I wash for 20 minutes with TBST, then rinse again briefly with TBST. HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? >3 HAVE YOU RUN A "NO PRIMARY" CONTROL? No DO YOU OBTAIN THE SAME RESULTS EVERY TIME? No WHAT STEPS HAVE YOU ALTERED? I have tried two different protein extractions. I have changed the proportion of Laemmli loading buffer. I have reduced the percentage of the gel. I have increased the transfer time. ADDITIONAL NOTES I'm hesitant to simply increase the concentration of the primary in the NCX and SERCA preps, in part because there are dark smears in the stacking gel areas of these blots. Also, the NCX and alpha2 antibodies are already used at a high concentration and I could easily use them up trying to get these protocols to work. I would be pleased to immediately try any recommendations you have, however.

    Answer

    I'm sorry to hear you are having problems with ab2817 and ab6495. Your detailed protocol was very useful to understand the source of the problem and it is clear your protocol and modifications were very thorough. My suspicions therefore lied with your samples, they are sheep derived and neither antibody has been tested in sheep. I therefore I checked the homology between the immunogen of ab2827 (canine protein) and the sheep protein and I found only 40% homology (119 aa out of 295aa), so I suspect that the antibody ab2827 is not detecting the protein. For ab6495, the homology between the rabbit NCX1 protein and the sheep NCX1 protein was so low that I couldn't find it when BLASTing with the rabbit protein the sheep genome. So I'm sorry to say that it seems that neither antibodies seem to work due to the nature of the samples (on the protocol aspect, ab6495 was tested at a 1:200 dilution with using 5S-protein A; with ECL dilutions may need to be considerably higher regardless of the samples). Please let me know if I can be of further assistance,
