Antigen/Purification: ExpandCollapse

The antigen is a phosphopeptide corresponding to amino acid residues surrounding the phospho-Thr52 of human ATF2.

The antibody is prepared from pooled rabbit serum by affinity purification via sequential chromatography on phospho and dephospho-peptide affinity columns.

Biological Significance: ExpandCollapse

The transcription factor ATF2 is a member of the ATF/CREB family of leucine zipper proteins. In response to stress stimuli, it activates a variety of gene targets that are involved in oncogenesis, and has been correlated with maintenance of a cancer cell phenotype (Vlahopoulos et al., 2008). Inhibiting ATF2 impedes melanoma development and elicits tumor suppressor function (Bhoumik et al., 2008). To act as a tumor suppressor, ATF2 must localize at the mitochondria, and phosphorylation at Thr52 by PKC? regulates this translocation (Lau et al., 2012).
