PGC-1-related coactivator (PRC), also known as peroxisome proliferator-activated receptor gamma coactivator-related protein 1, is a 1,664 amino acid nuclear protein. PRC is involved in the coactivation of nuclear genes involved in mitochondrial biogenesis and cell growth. PRC acts as a transcriptional coactivator of CREB-1 and NRF-1 by interacting directly with CREB-1 and NRF-1 genes. Up-regulated by serum, PRC is present at high levels in skeletal muscle and heart and at moderate levels in kidney, spleen, thymus, intestine, placenta, lung, brain and colon. PRC has one RNA recognition motif (RRM) domain, which can bind directly to RNA. PRC is exists as two named isoforms produced by alternative splicing. |
