CSK is a non-receptor tyrosine protein kinase that critically regulates cell growth, differentiation, migration and immune responses by phosphorylating tyrosine residues in the C-terminal tail of Src family kinases (SFK) . This induces an inactive conformation through intramolecular interactions with the SH2 domain of SFK. CSK Protein, Human (sf9, GST) is the recombinant human-derived CSK protein, expressed by Sf9 insect cells , with N-GST labeled tag.
