CRKL(v-crk sarcoma virus CT10 oncogene homolog(avian)-like) also called ONCOGENE CRKL, encodes a 303-amino acid polypeptide with a predicted molecular mass of 36 kD. While CRKL is not the human homolog of CRK, it is similar to protein-tyrosine kinases with SH2 and SH3(src homology) domains. By fluorescence in situ hybridization, the CRKL gene is localized to chromosome 22q11, centromeric of the chronic myelogenous leukemia breakpoint region. Senechal et al.(1996) showed that CRKL becomes phosphorylated when overexpressed, activates Ras-dependent and JNK pathways, and transforms fibroblasts. The authors also found CRKL to be a substrate for the BCR-ABL tyrosine kinase, leading them to conclude thatCRKL is a tyrosine kinase and an oncogene. Crkl was required for normal cellular responses to Fgf8, including survival and migration, Erk activation, and target gene expression.
