Human PGC1 alpha Alexa Fluor™ Plus 555‑conjugated Antibody

PGC1 alpha (PPAR-gamma Coactivator 1 alpha; also LEM6) is a 97-120 kDa member of the PGC-1 family of proteins. It is expressed in select cell types, including brown adipocytes, skeletal muscle and hepatocytes. PGC1 alpha participates in both RNA processing and transcriptional coactivation in conjunction with multiple nuclear hormone receptors such as PPAR gamma, RAR and TR. Human PCG1 alpha is 798 amino acids (aa) in length. It contains an LxxLL nuclear receptor binding motif (aa 144-148), one PPAR-gamma interaction domain (aa 293-339), two NLSs and an RNA binding/processing region (aa 566-710). PGC1 alpha 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 PGC1 alpha activity. This latter effect is achieved by an initial Ser571 phosphorylation, followed by GCN5 binding and subsequent PCG1 alpha acetylation that promotes PGC-1 alpha dissociation from target gene promoters.
