CHK/HYL is a non-receptor tyrosine kinase that belongs to CSK (C-terminal Src kinase) family, Northern blotting and RT-PCR analyses showed that CHK/HYL was expressed in large spectrum of hematopoietic cells except for erythroid cells and brain. To explore the function of CHK/HYL in hematopoietic cells, we generated CHK/HYL deficient mice. The mutant mice were apparently normal and fertile, while CSK knockout mice died until E11.5 from a defect in the neural tube formation. Hematological observations including blood counts and FAGS analysis showed no significant abnormalities in CHK/HYL mutant mice. CHK/HYL did not affect the activity of Src, Hck, and Fgr in cultured bone marrow cells, although CSK negatively regulates Src family kinases. These results suggest that CHK/HYL might not have the same function as CSK.
