靶标

  • 功能

    Essential for the maintenance of chromosomal stability through efficient stabilization of microtubule capture at kinetochores. Plays a key role in the movement of chromosomes toward the metaphase plate during mitosis. Is a slow plus end-directed motor whose activity is essential for metaphase chromosome alignment. Couples chromosome position to microtubule depolymerizing activity. The highly processive microtubule-dependent motor activity of CENPE serves to power chromosome congression and provides a flexible, motile tether linking kinetochores to dynamic spindle microtubules. Necessary for the mitotic checkpoint signal at individual kinetochores to prevent aneuploidy due to single chromosome loss. Required for the efficient recruitment of BUBR1, MAD1 and MAD2 to attached and newly unattached kinetochores. Stimulates mammalian BUBR1 kinase activity. Accumulates just before mitosis at the G2 phase of the cell cycle.

  • 疾病相关

    Microcephaly 13, primary, autosomal recessive

  • 序列相似性

    Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family.
    Contains 1 kinesin motor domain.

  • 结构域

    The protein is composed of a N-terminal kinesin-motor domain involved in the chromosome movements, a long coil-coiled region involved in the homodimerization and an inhibitory C-tail involved in autoinhibition of the N-terminal catalytic part.

  • 翻译后修饰

    The C-terminal inhibitory domain is phosphorylated. Phosphorylation relieves autoinhibition of the kinetochore motor.
    Sumoylated with SUMO2 and SUMO3. The sumoylation mediates the association to the kinetochore.

  • 细胞定位

    Chromosome, centromere, kinetochore. Cytoplasm, cytoskeleton, spindle. Associates with kinetochores during congression (as early as prometaphase), relocates to the spindle midzone at anaphase, and is quantitatively discarded at the end of the cell division.

      ab5093 at 1/500 staining human fibrosarcoma (HT1080) cells by ICC/IF. The cells were treated with 0.1-0.2ug/mL colcemid for 45-60 minutes, then swollen in hypotonic buffer for 8 minutes and centrifuged onto glass slides. Cells were blocked in 1X PBS + 1% BSA + 0.5% Triton X-100 (blocking buffer) for 30 minutes at room temperature. The antibodies were diluted 1/300-1/500 in blocking buffer and incubated overnight at 4 degrees C. ab5093 was detected with Alexa Fluor 488-donkey anti-mouse for 1-2 hours at room temperature.

    Answer

    Thank you for your enquiry. I am sorry to hear that one of your customers has been having difficulties with this antiserum. I have had a look at your submitted technical questionnaire and I have a few comments. Your customers western blot protocol is not significantly different from one I would recommend. I would like to suggest the use of 5% BSA as a blocking solution or even PBST or TBST alone to improve your chances of signal. It may be that your customer is out competing the binding of the antiserum and therefore achieving poor signal. According to our datasheet "this antibody is only suitable for WB if IP is performed first". Therefore it is highly likely that your customer is unable to detect this protein by western blot on whole cell HeLa lysates because it is beyond the detection threshold of this antiserum, as described on our datasheet. I hope this information helps. Please do not hesitate to contact me should you require further assistance.
