该基因编码具有转化能力的猫肉瘤逆转录病毒蛋白的人类细胞对应物。该基因产物具有酪氨酸特异性蛋白激酶活性，该活性是维持细胞转化所必需的。它的染色体定位与急性早幼粒细胞白血病患者中发现的一种特殊易位事件有关，但它也参与正常造血以及生长因子和细胞因子受体信号传导。选择性剪接导致编码不同亚型的多个变体。[由RefSeq提供，2009年1月]
This gene encodes the human cellular counterpart of a feline sarcoma retrovirus protein with transforming capabilities. The gene product has tyrosine-specific protein kinase activity and that activity is required for maintenance of cellular transformation. Its chromosomal location has linked it to a specific translocation event identified in patients with acute promyelocytic leukemia but it is also involved in normal hematopoiesis as well as growth factor and cytokine receptor signaling. Alternative splicing results in multiple variants encoding different isoforms.[provided by RefSeq, Jan 2009]
