PGC-1 alpha, phosphorylated (S571) (Peroxisome Proliferator Activated Receptor gamma Coactivator 1 alpha, PPAR gamma Coactivator 1 alpha, PPARGC-1 alpha, PPARGC1A, PGC1 alpha, PGC1A, PGC1, PGC-1, Ligand Effect Modulator 6, LEM6)

PGC-1a is a 97-120kD member of the PGC-1 family of proteins. It is expressed in select cell types, including brown adipocytes, skeletal muscle and hepatocytes. PGC-1a participates in both RNA processing and transcriptional coactivation in conjunction with multiple nuclear hormone receptors such as PPARg, RAR and TR. Human PCG-1a is 798aa in length. It contains an LxxLL nuclear receptor binding motif aa144-148, one PPAR-g interaction domain aa293-339, two NLSs and an RNA binding/processing region aa566-710. PGC-1a activity is regulated by phosphorylation. AMPK is known to phosphorylate Thr178 and Ser539, promoting cotranscriptional activity. Conversely, Akt-mediated phosphorylation at Ser571 is reported to downregulate PGC-1a activity. This latter effect is achieved by an initial Ser571 phosphorylation, followed by GCN5 binding and subsequent PCG-1a acetylation that promotes PGC-1a dissociation from target gene promoters.\n\nApplications:\nSuitable for use in Western Blot.
