title: [Obtaining a full-length encoding cDNA of Csk family tyrosine kinase from human lymphocytes].
abstract: Tyrosine kinases of Csk family play important role in the cell growth regulation and normal cell differentiation and also can participate in the process of cancer genesis as oncoproteins. The main function of these tyrosine kinases is the phosphorylation of the Src family tyrosine kinases at their carboxyl terminus, which is the basis of their activity negative regulation. The disturbance of the csk gene expression leads to the increase of the Src tyrosine kinase activity. We have cloned a full-length encoding cDNA of the tyrosine kinase csk gene of human lymphocytes. 1.6-kilobase cDNA encodes the protein, which consists of 12 exons with conserved SH2 and SH3 domains. The homology between this protein and human Csk tyrosine kinase is 99%. A full-length DNA-copy of human lymphocytes RNA can be used for the analysis of csk gene structure in normal and pathologically changed human cells.
