AXL Antibody – Mouse Monoclonal

The protein encoded by this gene is a member of the Tyro3-Axl-Mer (TAM) receptor tyrosine kinase subfamily. The encoded protein possesses an extracellular domain which is composed of two immunoglobulin-like motifs at the N-terminal, followed by two fibronectin type-III motifs. It transduces signals from the extracellular matrix into the cytoplasm by binding to the vitamin K-dependent protein growth arrest-specific 6 (Gas6). This gene may be involved in several cellular functions including growth, migration, aggregation and anti-inflammation in multiple cell types. Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jul 2013]

AXL: a receptor tyrosine kinase that may function as a signal transducer between specific cell types of mesodermal origin. Interacts with SKP1. Overexpression in tissue culture causes oncogenic transformation. Overexpressed in several cancers including thyroid, ovarian, gastric, ER+ breast cancer and acute myeloid leukemia, where it is associated with poor prognosis. 2 isoforms of the human protein are produced by alternative splicing.
