Scientific Background: Axl (UFO) is a protein-tyrosine kinase of the TK group and Axl family. It is a receptor kinase for its ligand growth arrest-specific gene-6 (GAS6), which is a growth factor that drives cell proliferation. GAS6 is a vitamin K-dependent protein structurally similar to Protein S (PROS1), which activates MERTK and TYRO3 but not Axl. The extracellular domain contains six N-linked glycosylation sites,and this generates two other post-translationally modified forms of 120 and 140 kDa represent partial and complete glycosylation, respectively. Phosphorylation of Y821 induces interactions with Grb2, PIK3R1, PIK3R2, and PLCG1.Some of Axl signalling pathways involve PI3K/Akt, Ras and ERK MAP kinases. It regulates cell survival and proliferation, preventing apoptosis, migration, cell adhesion, cell aggregation and homophillic binding. Mutation of Axl at E63R, E66R, and T84R reduces its affinity for GAS6. Axl is expressed most tissue and cell types, with highest in endothelial cells, heart and skeletal muscle, liver, kidney, testis, platelets, myelomonocytic cells, hippocampus, and cerebellum. Axl is overexpressed in numerous human cancers, including thyroid carcinomas, myeloproliferative disorders, prostatic carcinoma cells, and breast cancer. Its up-regulation in expression contributes to metastasis and invasion, and in most cases negatively correlates with prognosis.
