Growth arrest-specific protein 6 (GAS6) is a vitamin K-dependent protein that plays an important role in the pathogenesis of autoimmune diseases. Ligand for tyrosine-protein kinase receptors AXL, TYRO3 and MER whose signaling is implicated in cell growth and survival, cell adhesion and cell migration. GAS6/AXL signaling plays a role in various processes such as endothelial cell survival during acidification by preventing apoptosis, optimal cytokine signaling during human natural killer cell development, hepatic regeneration, gonadotropin-releasing hormone neuron survival and migration, platelet activation, or regulation of thrombotic responses.Can bridge virus envelope phosphatidylserine to the TAM receptor tyrosine kinase Axl to mediate viral entry by apoptotic mimicry. Plays a role in Dengue cell entry by apoptotic mimicry. Plays a role in Vaccinia virus cell entry by apoptotic mimicry. Plays a role in ebolavirus and marburgvirus cell entry by apoptotic mimicry.
