Gene Information

bovine ... Stat5A(282375)

General description

The STAT proteins (signal transducer and activator of transcription) comprise a family of transcription factors. STATs are activated through tyrosine phosphorylation, mainly by JAK kinases, which results in their dimerization, nuclear translocation and regulation of gene expression. STAT5 activity is induced by numerous cytokines and growth factors. While STAT5A and STAT5B share 96% amino acid homology, the two isoforms have distinct physiological functions. Phosphorylation of tyrosine 694/699 is a key marker of STAT5A/B activation.

Specificity

Phospho-STAT5A/B (Tyr694/699).

Immunogen

Epitope: pTyr694/699
KLH-conjugated, synthetic peptide containing the sequence DGpYVK in which pY corresponds to phospho-tyrosine at residue 694 of human STAT5A or residue 699 of STAT5B.

Application

Detect phospho-STAT5A/B (Tyr694/699) using this Anti-phospho-STAT5A/B (Tyr694/699) Antibody, clone A11W validated for use in WB.
