Rabbit FAK Polyclonal Antibody | anti-PTK2 antibody
Anti-FAK antibody
Background: FAK,(Focal Adhesion Kinase), also known as PTK2(protein tyrosine kinase 2), is a protein that, in humans, is encoded by the PTK2 gene. PTK2 is a focal adhesion-associated protein kinase involved in cellular adhesion(how cells stick to each other and their surroundings) and spreading processes(how cells move around). It has been shown that when FAK was blocked, breast cancer cells became less metastastic due to decreased mobility. This gene encodes a cytosolic protein tyrosine kinase that is found concentrated in the focal adhesions that form among cells attaching to extracellular matrix constituents. The encoded protein is a member of the FAK subfamily of protein tyrosine kinases that included PYK2 but lacks significant sequence similarity to kinases from other subfamilies. With the exception of certain types of blood cells, most cells express FAK. FAK tyrosine kinase activity can be activated, which plays a key important early step in cell migration. FAK activity elicits intracellular signal transduction pathways that promote the turn-over of cell contacts with the extracellular matrix, promoting cell migration. FAK is required during development, with loss of FAK resulting in lethality. It seems to be a paradox that FAK is not absolutely required for cell migration, and may play other roles in the cell, including the regulation of the tumor suppressor p53. At least four transcript variants encoding four different isoforms have been found for this gene, but the full-length natures of only two of them have been determined. FAK is a protein of 125 kD recruited as a participant in focal adhesion dynamics between cells, and has a role in motility and cell survival. FAK is a highly conserved, non-receptor tyrosine kinase originally identified as a substrate for the oncogene protein tyrosine kinase v-src. This cytosolic kinase has been implicated in diverse cellular roles including cell locomotion, mitogen response and cell survival. FAK is typically located at structures known as focal adhesions, these are multi-protein structures that link the extracellular matrix(ECM) to the cytoplasmic cytoskeleton. Additional components of focal adhesions include actin, filamin, vinculin, talin, paxillin and tensin.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a cytoplasmic protein tyrosine kinase which is found concentrated in the focal adhesions that form between cells growing in the presence of extracellular matrix constituents. The encoded protein is a member of the FAK subfamily of protein tyrosine kinases but lacks significant sequence similarity to kinases from other subfamilies. Activation of this gene may be an important early step in cell growth and intracellular signal transduction pathways triggered in response to certain neural peptides or to cell interactions with the extracellular matrix. Several transcript variants encoding different isoforms have been found for this gene, but the full-length natures of only three of them have been determined. [provided by RefSeq, Dec 2010]
Uniprot Description
FAK: a tyrosine kinase of the FAK family required for cell migration and contact-dependent survival signaling. Activated by tyrosine-phosphorylation in response to either integrin clustering induced by cell adhesion or antibody cross-linking, or via G-protein coupled receptor (GPCR) occupancy by ligands such as bombesin or lysophosphatidic acid, or via LDL receptor occupancy. Downstream of integrins and Src, upstream of Ras/MAPK. Localizes to focal adhesions that form between cells growing in the presence of extracellular matrix constituents. Interacts with CAS family members and with GIT1, SORBS1 and BCAR3. Interacts with Shb. Required for full Ras transformation of fibroblasts. Increased expression in breast and other cancers, related to chromosome 8q amplification. Overexpression and activation associated with increased migration, invasion and progression of ovarian cancer, and with progression in hepatocellular carcinoma, thyroid cancer, and acute myelogenous leukemia. siRNA increases chemosensitivity of pancreatic adenocarcinoma xenografts. Inhibitor: ISI15421 (antisense). Four splice-variant isoforms have been observed.
