General annotation (Comments)

Function

Non-receptor protein-tyrosine kinase implicated in signaling pathways involved in cell motility, proliferation and apoptosis. 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. Plays a potential role in oncogenic transformations resulting in increased kinase activity.

Catalytic activity

ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.

Subunit structure

Interacts with CAS family members and with GIT1, SORBS1 and BCAR3. Interacts with RGNEF and SHB By similarity. Interacts with TGFB1I1.

Subcellular location

Cell junctionfocal adhesion. Cell membrane; Peripheral membrane protein; Cytoplasmic side. Note: Constituent of focal adhesions.

Tissue specificity

Expressed in all organs tested, in lymphoid cell lines, but most abundantly in brain. Ref.4

Domain

The first Pro-rich domain interacts with the SH3 domain of CRK-associated substrate (BCAR1) and CASL By similarity.

The carboxy-terminal region is the site of focal adhesion targeting (FAT) sequence which mediates the localization of FAK1 to focal adhesions.

Post-translational modification

Phosphorylated on 6 tyrosine residues upon activation. Ref.7 Ref.8 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13

Sequence similarities

Belongs to the protein kinase superfamily. Tyr protein kinase family. FAK subfamily.

Contains 1 FERM domain.

Contains 1 protein kinase domain.
