纯度Immunogen affinity purified
纯化说明Purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using (i) a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated PYK 2, (ii) a generic tyrosine phosphorylated peptide to remove antibody that is reactive with phosphotyrosine, irrespective of the sequence, and (iii) a phosphopeptide derived from the corresponding region of Focal Adhesion Kinase (a PYK 2-related protein) to remove antibody that is reactive with phosphorylated Focal Adhesion Kinase protein. The final product is generated by affinity chromatography using a PYK 2-derived peptide that is phosphorylated at tyrosines 579 and 580.

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.

Peptide Competition: Cell extracts prepared from chick embryo fibroblasts treated with vanadate were plated on fibronectin with (lanes 1-5) or without (lane 6) transfection of a PYK 2 expression vector and resolved by SDS PAGE on a 10% Tris-glycine gel. The proteins were then transferred to nitrocellulose. Membranes were incubated with 0.50
µg/mL ab4807, following prior incubation in the presence of the phosphopeptide immunogen (1), the absence of the phosphopeptide immunogen (2, 6), the non phosphopeptide corresponding to the PYK 2 phosphopeptide (3), the phosphopeptide corresponding to PYK 2 [pY579] (4), and the phosphopeptide corresponding to PYK 2 [pY580] (5). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and signals were detected using the Tropix WesternStar method. The data show that only the dual-phosphopeptide corresponding to this site blocks the antibody signal, not the corresponding mono phosphopeptides, t
