Csk - c-src tyrosine kinase

Predicted to enable several functions, including enzyme binding activity; identical protein binding activity; and non-membrane spanning protein tyrosine kinase activity. Acts upstream of or within negative regulation of cell population proliferation. Located in cell-cell junction. Is expressed in several structures, including Peyer's patch; central nervous system; genitourinary system; gut; and liver and biliary system. Orthologous to human CSK (C-terminal Src kinase).
