Cell Res. 317:1860-1871(2011). CC -!- FUNCTION: Non-receptor protein-tyrosine kinase that regulates CC reorganization of the actin cytoskeleton, cell polarization, cell CC migration, adhesion, spreading and bone remodeling. Plays a role in the CC regulation of the humoral immune response, and is required for normal CC levels of marginal B-cells in the spleen and normal migration of CC splenic B-cells. Required for normal macrophage polarization and CC migration towards sites of inflammation. Regulates cytoskeleton CC rearrangement and cell spreading in T-cells, and contributes to the CC regulation of T-cell responses. Promotes osteoclastic bone resorption; CC this requires both PTK2B/PYK2 and SRC. May inhibit differentiation and CC activity of osteoprogenitor cells. Functions in signaling downstream of CC integrin and collagen receptors, immune receptors, G-protein coupled CC receptors (GPCR), cytokine, chemokine and growth factor receptors, and CC mediates responses to cellular stress. Forms multisubunit signaling CC complexes with SRC and SRC family members upon activation; this leads CC to the phosphorylation of additional tyrosine residues, creating CC binding sites for scaffold proteins, effectors and substrates. CC Regulates numerous signaling pathways. Promotes activation of CC phosphatidylinositol 3-kinase and of the AKT1 signaling cascade. CC Promotes activation of NOS3. Regulates production of the cellular CC messenger cGMP. Promotes activation of the MAP kinase signaling CC cascade, including activation of MAPK1/ERK2, MAPK3/ERK1 and MAPK8/JNK1. CC Promotes activation of Rho family GTPases, such as RHOA and RAC1. CC Recruits the ubiquitin ligase MDM2 to P53/TP53 in the nucleus, and CC thereby regulates P53/TP53 activity, P53/TP53 ubiquitination and CC proteasomal degradation. Acts as a scaffold, binding to both PDPK1 and CC SRC, thereby allowing SRC to phosphorylate PDPK1 at 'Tyr-9, 'Tyr-373', CC and 'Tyr-376' (By similarity). Promotes phosphorylation of NMDA CC receptors by SRC family members, and thereby contributes to the CC regulation of NMDA receptor ion channel activity and intracellular CC Ca(2+) levels. May also regulate potassium ion transport by CC phosphorylation of potassium channel subunits. Phosphorylates SRC; this CC increases SRC kinase activity. Phosphorylates ASAP1, NPHP1, KCNA2 and CC SHC1. Promotes phosphorylation of ASAP2, RHOU and PXN; this requires CC both SRC and PTK2/PYK2 (By similarity). {ECO:0000250, CC ECO:0000269|PubMed:10881171, ECO:0000269|PubMed:11238453, CC ECO:0000269|PubMed:12960403, ECO:0000269|PubMed:14739300, CC ECO:0000269|PubMed:17537919, ECO:0000269|PubMed:17698736, CC ECO:0000269|PubMed:17846174, ECO:0000269|PubMed:18587400, CC ECO:0000269|PubMed:19561089, ECO:0000269|PubMed:19880522, CC ECO:0000269|PubMed:20688918, ECO:0000269|PubMed:21640103}.

Activated by autophosphorylation at Tyr-402; this CC creates a binding site for SRC family kinases and leads to CC phosphorylation at additional tyrosine residues. Phosphorylation at CC Tyr-402, Tyr-579 and Tyr-580 is required for optimal kinase activity. CC {ECO:0000269|PubMed:17537919, ECO:0000269|PubMed:20688918}. CC -!- SUBUNIT: Homodimer, or homooligomer.

Cell projection, lamellipodium CC {ECO:0000250}. Cytoplasm, cell cortex {ECO:0000250}. Nucleus CC {ECO:0000250}. Note=Colocalizes with integrins at the cell periphery CC (By similarity). Interaction with NPHP1 induces the membrane- CC association of the kinase. Colocalizes with PXN at the microtubule- CC organizing center. The tyrosine phosphorylated form is detected at CC cell-cell contacts. {ECO:0000250}. CC -!- PTM: Phosphorylated on tyrosine residues in response to various stimuli CC that elevate the intracellular calcium concentration; this activation CC is indirect and may be mediated by production of reactive oxygen CC species (ROS). Tyr-402 is the major autophosphorylation site, but other CC kinases can also phosphorylate Tyr-402. Autophosphorylation occurs in CC trans, i.e. one subunit of the dimeric receptor phosphorylates tyrosine CC residues on the other subunit. Phosphorylation at Tyr-402 promotes CC interaction with SRC and SRC family members, leading to phosphorylation CC at Tyr-579; Tyr-580 and Tyr-881. Phosphorylation at Tyr-881 is CC important for interaction with GRB2. Phosphorylated on tyrosine CC residues upon activation of FGR and PKC. Recruitment by NPHP1 to cell CC matrix adhesions initiates Tyr-402 phosphorylation. In monocytes, CC adherence to substrata is required for tyrosine phosphorylation and CC kinase activation. Angiotensin II, thapsigargin and L-alpha- CC lysophosphatidic acid (LPA) also induce autophosphorylation and CC increase kinase activity. Phosphorylation by MYLK promotes ITGB2 CC activation and is thus essential to trigger neutrophil transmigration CC during lung injury. Dephosphorylated by PTPN12 (By similarity). CC {ECO:0000250}. CC -!- DISRUPTION PHENOTYPE: Mice are born at the expected Mendelian rate, CC appear normal and are fertile. Mice display increased bone formation CC and high bone mass, due to defects in osteoclastic bone resorption. CC Osteoclasts display defects in actin cytoskeleton reorganization, plus CC altered Rho activity, microtubule stabilization and podosome CC organization. Mice also display increased differentiation and activity CC of osteoprogenitor cells. Macrophages from mutant mice display defects CC in their responses to chemokines, including defects in cell CC polarization, actin cytoskeleton reorganization, directed migration CC towards sites of inflammation, but also defects in the regulation of CC intracellular Ca(2+) levels, phosphatidylinositol 3-kinase activity and CC inositol 1,4,5-trisphosphate production. Mutant mice have normal B-cell CC polulations in bone marrow, lymph nodes and blood, but lack marginal CC zone B-cells in the spleen. {ECO:0000269|PubMed:10881171, CC ECO:0000269|PubMed:12960403, ECO:0000269|PubMed:17537919, CC ECO:0000269|PubMed:17846174}.
