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.
