| abstractText | Several members of the Src family of non-receptor tyrosine kinases are expressed at high levels in embryonic neural tissues as well as in adult brain. Relatively little has been known, however, about their roles in neural development. Attempts to clarify this by production of mutant mice have been unsuccessful because of gene redundancy. We earlier isolated a new cytoplasmic protein tyrosine kinase, Csk, and showed that it inactivates uniquely all members of non-receptor tyrosine kinases in vitro. Here, we have generated Csk-deficient mouse embryos and shown that Csk is indeed an indispensable negative regulator for all non-receptor tyrosine kinases in vivo, and that regulated activity of these kinases is essential for normal development of mice at the neural stage. The signaling pathway through Src-family kinases during neurulation is also discussed. |
