General annotation (Comments)
| Function | Non-receptor tyrosine-protein kinase that transmits signals from cell surface receptors devoid of kinase activity and contributes to the regulation of immune responses, including neutrophil, monocyte, macrophage and mast cell functions, cytoskeleton remodeling in response to extracellular stimuli, phagocytosis, cell adhesion and migration. Promotes mast cell degranulation, release of inflammatory cytokines and IgE-mediated anaphylaxis. Acts downstream of receptors that bind the Fc region of immunoglobulins, such as MS4A2/FCER1B, FCER1G and FCGR2. Acts downstream of ITGB1 and ITGB2, and regulates actin cytoskeleton reorganization, cell spreading and adhesion. Depending on the context, activates or inhibits cellular responses. Functions as negative regulator of ITGB2 signaling, phagocytosis and SYK activity in monocytes (Ref.10). Required for normal ITGB1 and ITGB2 signaling, normal cell spreading and adhesion in neutrophils and macrophages (Ref.7 and Ref.8). Functions as positive regulator of cell migration and regulates cytoskeleton reorganization via RAC1 activation (Ref.11). Phosphorylates SYK (in vitro) and promotes SYK-dependent activation of AKT1 and MAP kinase signaling (Ref.15). Phosphorylates PLD2 in antigen-stimulated mast cells, leading to PLD2 activation and the production of the signaling molecules lysophosphatidic acid and diacylglycerol. Promotes activation of PIK3R1. Phosphorylates FASLG, and thereby regulates its ubiquitination and subsequent internalization. Phosphorylates ABL1. Promotes phosphorylation of CBL, CTTN, PIK3R1, PTK2/FAK1, PTK2B/PYK2 and VAV2. Phosphorylates HCLS1 that has already been phosphorylated by SYK, but not unphosphorylated HCLS1. Ref.6 Ref.7 Ref.8 Ref.9 Ref.10 Ref.11 Ref.14 Ref.15 |
| Catalytic activity | ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. Ref.11 |
| Enzyme regulation | Activated by autophosphorylation. Prior phosphorylation at Tyr-511 by SRC inhibits ulterior autophosphorylation at Tyr-400. Activated by phorbol myristate acetate, phosphatidic acid and poly-Lys. Binding (via SH2 domain) of HCLS1 that is already phosphorylated by SYK strongly increases kinase activity. |
| Subunit structure | Interacts with ITGB1, ITGB2, MS4A2/FCER1B, FCER1G and FCGR2. Interacts (via SH2 domain) with SYK (tyrosine phosphorylated). Interacts (via SH2 domain) with FLT3 (tyrosine phosphorylated). Interacts with PTK2/FAK1. Interacts (via SH2 domain) with HCLS1 (tyrosine phosphorylated by SYK). Interacts with SIRPA and PTPNS1. Interacts (not phosphorylated on tyrosine residues) with CBL; FGR tyrosine phosphorylation promotes dissociation By similarity. Ref.8 Ref.9 Ref.10 Ref.11 Ref.12 Ref.14 Ref.15 |
| Subcellular location | Cell membrane; Lipid-anchor; Cytoplasmic side Probable. Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cell projection › ruffle membrane. Cytoplasm › cytosol. Cytoplasm › cytoskeleton. Mitochondrion inner membrane By similarity. Mitochondrion intermembrane space By similarity. Note: Detected in mitochondrial intermembrane space and at inner membranes By similarity. Colocalizes with actin fibers at membrane ruffles. Detected at plasma membrane lipid rafts. Ref.11 |
| Post-translational modification | Ubiquitinated. Becomes ubiquitinated in response to ITGB2 signaling; this does not lead to degradation By similarity. Phosphorylated. Autophosphorylated on tyrosine residues. Becomes phosphorylated in response to FCGR2 engagement, cell adhesion and signaling by ITGB2. Prior phosphorylation at Tyr-511 by SRC inhibits ulterior autophosphorylation at Tyr-400 By similarity. |
| Disruption phenotype | No visible phenotype. Mice lacking both Fgr and Hck are normal and fertile, but show increased susceptibility to infection with Listeria monocytogenes. In addition, their polymorphonuclear leukocytes show defects in cell spreading and adhesion. Ref.6 Ref.7 |
| Sequence similarities | Belongs to the protein kinase superfamily. Tyr protein kinase family. SRC subfamily. Contains 1 protein kinase domain. Contains 1 SH2 domain. Contains 1 SH3 domain. |
