Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase.

存放说明Shipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
Constituents: PBS, 50% Glycerol
Concentration information loading...
纯度Immunogen affinity purified
纯化说明Purified from rabbit serum by epitope-specific chromatography. Any reactivity towards the non-tyrosine phosphorylated PYK 2 protein, the corresponding phosphotyrosine (577) of the Focal Adhesion Kinase protein, or generic phosphotyrosine has been eliminated through a series of preadsorption steps.
Our Abpromise guarantee covers the use of ab4806 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

功能Involved in calcium induced regulation of ion channel and activation of the map kinase signaling pathway. May represent an important signaling intermediate between neuropeptide activated receptors or neurotransmitters that increase calcium flux and the downstream signals that regulate neuronal activity. Interacts with the SH2 domain of Grb2. May phosphorylate the voltage-gated potassium channel protein Kv1.2. Its activation is highly correlated with the stimulation of c-Jun N-terminal kinase activity. Involved in osmotic stress-dependent SNCA 'Tyr-125' phosphorylation. In concert with SRC, plays an important role in osteoclastic bone resorption. Both the formation of a SRC-PTK2B complex, and SRC kinase activity are necessary for this function. The Tyr-402 phosphorylated form serves as a docking site for SRC and is important for the organization of the osteoclast actin cytoskeleton and attachment sites and for bone resorption.
组织特异性Most abundant in the brain, with highest levels in amygdala and hippocampus. Low levels in kidney. Also expressed in spleen and lymphocytes.
序列相似性Belongs to the protein kinase superfamily. Tyr protein kinase family. FAK subfamily.
Contains 1 FERM domain.
Contains 1 protein kinase domain.
翻译后修饰Phosphorylated on tyrosine residues in response to various stimuli that elevate the intracellular calcium concentration, as well as by PKC activation. Recruitment by nephrocystin to cell matrix adhesions initiates Tyr-402 phosphorylation. In monocytes, adherence to substrata is required for tyrosine phosphorylation and kinase activation. Angiotensin II, thapsigargin and L-alpha-lysophosphatidic acid (LPA) also induce autophosphorylation and increase kinase activity.
细胞定位Cytoplasm. Cell membrane. Interaction with nephrocystin induces the membrane-association of the kinase.

Cell extracts prepared from chick embryo fibroblasts expressing PYK 2 and plated on fibronectin were resolved by SDS-PAGE on a 10% Tris-glycine gel. The proteins were then transferred to nitrocellulose. Membranes were incubated with 0.5
µg/mL ab4806, following prior incubation in the absence (none) or presence of the peptide immunogen, the nonphosphopeptide corresponding to the PYK 2 phosphopeptide, the phosphopeptide corresponding to tyrosine 577 on FAK, the phosphopeptide corresponding to tyrosine 579 on PYK 2, and a generic phosphotyrosine containing peptide. After washing, membranes were incubated with goat F(ab’)2 anti rabbit IgG alkaline phosphatase and bands were detected using the Tropix WesternStar detection method. The data show that only the phosphopeptide corresponding to this site blocks the antibody signal, therefore demonstrating the specificity of the ab4806 antibody for this phosphorylated residue. Cell extracts prepared from chick embryo
Extracts prepared from CEFs (1) or CEFs expressing PYK2 and plated on fibronectin (2-7) were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4oC, then were incubated with PYK2 (phospho Y580) antibody for two hours at room temperature in a 1% BSA-TBST buffer, following prior incubation with: no peptide (1, 2), the non-phosphopeptide corresponding to the immunogen (3), the phosphopeptide corresponding to PYK2 (phospho Y579) (4), a phosphopeptide derived from the corresponding region of FAK (5), a generic phosphotyrosine-containing peptide (6) or, the phosphopeptide immunogen (7). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG HRP conjugate and bands were detected using the Pierce SuperSignal method.
The data show that only the peptide corresponding to PYK2 (phospho Y580) completely blocks the antibody signal, thereby demonstrating the specificity of the antibody.
