Function
TYRO3_HUMAN Receptor tyrosine kinase that transduces signals from the extracellular matrix into the cytoplasm by binding to several ligands including TULP1 or GAS6. Regulates many physiological processes including cell survival, migration and differentiation. Ligand binding at the cell surface induces dimerization and autophosphorylation of TYRO3 on its intracellular domain that provides docking sites for downstream signaling molecules. Following activation by ligand, interacts with PIK3R1 and thereby enhances PI3-kinase activity. Activates the AKT survival pathway, including nuclear translocation of NF-kappa-B and up-regulation of transcription of NF-kappa-B-regulated genes. TYRO3 signaling plays a role in various processes such as neuron protection from excitotoxic injury, platelet aggregation and cytoskeleton reorganization. Plays also an important role in inhibition of Toll-like receptors (TLRs)-mediated innate immune response by activating STAT1, which selectively induces production of suppressors of cytokine signaling SOCS1 and SOCS3.[1] [2]

Publication Abstract from PubMed
The receptor Tyro3 together with Axl and Mer form the Axl/Tyro3 family of receptor tyrosine kinases. Members of this family play essential roles in spermatogenesis, immunoregulation, and phagocytosis. Gas6, the product of growth arrest-specific gene, activates the kinase activity of all three receptors. Here, we report the first biochemical and structural characterization of a member of this family, namely of a fragment spanning the two N-terminal Ig domains of the extracellular part of human Tyro3. Its ligand binding specificity profile is identical to the activation profile of the native receptor. The 1.95-A crystal structure suggests a common ligand-binding site in this receptor family located at the interface of the Ig domains and unusually rich in cis-prolines. Furthermore, both in the crystal and in solution we observed the ligand-independent dimerization of the receptor fragment. This homophilic interaction emphasizes previous functional reports, which hinted that in addition to signal transduction, members of this family of receptors might participate in cell adhesion.
