Specificity
This antibody recognises an epitope within the C-terminal (CT) region of CSK, also known as c-src tyrosine kinase, Tyrosine-protein kinase CSK, p50CSK or Protein-tyrosine kinase CYL. CSK is a cytoplasmic tyrosine kinase ubiquitously expressed as two mRNA species , which down-regulates the activity of the c-src oncoprotein. CSK is expressed in lung tissues and by macrophages and is highly conserved across species suggesting a role in important regulatory functions (Bräuninger et al. 1992).
