Functioni

Non-receptor tyrosine-protein kinase found in hematopoietic cells that transmits signals from cell surface receptors and plays an important role in the regulation of innate immune responses, including neutrophil, monocyte, macrophage and mast cell functions, phagocytosis, cell survival and proliferation, cell adhesion and migration. Acts downstream of receptors that bind the Fc region of immunoglobulins, such as FCGR1A and FCGR2A, but also CSF3R, PLAUR, the receptors for IFNG, IL2, IL6 and IL8, and integrins, such as ITGB1 and ITGB2. During the phagocytic process, mediates mobilization of secretory lysosomes, degranulation, and activation of NADPH oxidase to bring about the respiratory burst. Plays a role in the release of inflammatory molecules. Promotes reorganization of the actin cytoskeleton and actin polymerization, formation of podosomes and cell protrusions. Inhibits TP73-mediated transcription activation and TP73-mediated apoptosis. Phosphorylates CBL in response to activation of immunoglobulin gamma Fc region receptors. Phosphorylates ADAM15, BCR, ELMO1, FCGR2A, GAB1, GAB2, RAPGEF1, STAT5B, TP73, VAV1 and WAS (By similarity).By similarity

Catalytic activityi

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

Enzyme regulationi

Subject to autoinhibition, mediated by intramolecular interactions involving the SH2 and SH3 domains. Kinase activity is also regulated by phosphorylation at regulatory tyrosine residues. Phosphorylation at Tyr-389 is required for optimal activity. Phosphorylation at Tyr-500 inhibits kinase activity (By similarity).By similarity

Post-translational modificationi

Phosphorylated on several tyrosine residues. Autophosphorylated. Becomes rapidly phosphorylated upon activation of the immunoglobulin receptors FCGR1A and FCGR2A. Phosphorylation at Tyr-389 increases kinase activity. Phosphorylation at Tyr-500 inhibits kinase activity. Kinase activity is not required for phosphorylation at Tyr-500, suggesting that this site may be a target of other kinases (By similarity).By similarity
Ubiquitinated by CBL, leading to its degradation via the proteasome.By similarity
Palmitoylation requires prior myristoylation. Palmitoylation is required for caveolar localization (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
