a non-receptor tyrosine kinase of the Fer family. Appears to be involved in normal hematopoiesis as well as the development of acute promyelocytic leukemia. Contains one SH2 and one FCH domain. Four LOF point mutations seen in colorectal cancer. Orthologous to v-fes from feline leukemia virus and v-fps from avian transforming virus. Mutant forms are angiogenic. Promotes survival during differentiation, and may act both to promote and inhibit tumors. May be disrupted in the t(15q+;17q-) found in acute promyelocytic leukemia, but the breakpoint does not occur within the gene. Note: This description may include information from UniProtKB.
