Protocols

Specificity / Sensitivity

Non-phospho-Src (Tyr416) (7G9) Mouse mAb detects endogenous levels of Src only when dephosphorylated at tyrosine 416. The antibody cross-reacts with other Src family members (Lyn, Fyn, Lck, Yes and Hck) dephosphorylated at equivalent sites.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Tyr416 of human Src.

Western Blotting

Western Blotting

Western blot analysis of extracts from pervanadate-treated (1 mM for 5 minutes) NIH/3T3 cells that have been stably transfected with a constitutively active form of Src (in which the regulatory tyrosine 527 residue has been mutated to phenylalanine), A431 cells and HepG2 cells, using Non-phospho-Src (Tyr416) (7G9 ) Mouse mAb (top), v-Src antibody (middle) or Phospho-Src (Tyr416) Antibody #2101 (bottom).

Background

The Src family of protein tyrosine kinases, which includes Src, Lyn, Fyn, Yes, Lck, Blk, and Hck, are important in the regulation of growth and differentiation of eukaryotic cells (1). Src activity is regulated by tyrosine phosphorylation at two sites, but with opposing effects. While phosphorylation at Tyr416 in the activation loop of the kinase domain upregulates enzyme activity, phosphorylation at Tyr527 in the carboxy-terminal tail by Csk renders the enzyme less active (2).
