Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

Phospho-Src (Ser17) Antibody recognizes endogenous levels of Src protein only when phosphorylated at Ser17.

Phospho-Src (Ser17) Antibody兔多抗能够识别内源性Ser17位点磷酸化的Src蛋白水平。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser17 of human Src protein. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

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).

Src家族蛋白酪氨酸激酶包括Src, Lyn, Fyn, Yes, Lck, Blk, Hck, 对调节真核细胞的生长和分化很重要(1)。Src的活性是通过两个酪氨酸位点的磷酸化来调控的,但是这两者的调控效应相反。激酶结构域的活化环中的Tyr416位点的磷酸化,能够上调酶活性;而蛋白羧基端尾部Tyr527位点被Csk磷酸化后,则会使酶的活性降低(2)。

Protein kinase A (PKA)-dependent phosphorylation of Src at Ser17 is thought to influence multiple signaling networks (3-5).
