Immunopharmacology Comments
CSK is an inhibitory regulator of Src family kinases, a family of protein tyrosine kinases indispensable to the initiation of signal transduction via ITAM-bearing immunoreceptors, and cytokine, growth factor, and pattern recognition receptor signalling. CSK phosphorylates an inhibitory tyrosine residue at the C terminus of Src kinases, leading to autoinhibition. CSK-induced Src kinase inhibition can also be mediated by binding to PEST family receptor tyrosine phosphatases [9], which are recognised modulators in immunity, autoimmunity, and autoinflammatory disorders.

Gene Expression and Pathophysiology Comments
An intronic CSK polymorphism (associated with increased CSK expression) is identified as a risk allele for SLE. Carriers of the risk allele show increased B-cell receptor (BCR)-mediated activation of mature B cells and a higher circulating immunoglobulin M level, compared to non-carriers [6].
Biologically Significant Variants
Type:  Single nucleotide polymorphism
Species:  Human
Description:  CSK intronic polymorphism rs34933034 is a risk allele for systemic lupus erythematosus.
