Carbonic Acid 250-254 C-terminal Src kinase Homo sapiens 29-35 7696183-3 1994 Biochemical and site-directed mutagenesis analyses revealed that a carboxy-terminal peptide of p54rak was phosphorylated by a cytoplasmic tyrosine kinase (CSK) and that, as in the Src family, it is the COOH-terminal tyrosine that is phosphorylated by CSK. Carbonic Acid 202-206 C-terminal Src kinase Homo sapiens 155-158
