PGC-1 (IPR034605)

Short name: PGC-1

Family relationships

Description

The PGC-1 family members, including PGC-1alpha, PGC-1beta and PRC, are transcriptional coactivators that regulate cell metabolic processes ranging from mitochondrial biogenesis to oxidative respiration [PMID: 20933024]. They target NRF-1, a transcription factor that binds to a palindromic sequence in the cytochrome c promoter and associate with the expression of many genes required for expression and function of the respiratory chain. They also bind to CREB (cAMP response element-binding protein) and ERRalpha (estrogen-related receptor alpha). However, knockout of individual components in the PGC-1 family can result in diverse phenotypes ranging from early embryonic lethality to complete viability with very mild effects on global mitochondrial content and function. They contain an N-terminal region with a nuclear receptor coactivator signature-LXXLL and a C-terminal region with a RS domain and a RNA recognition motif [PMID: 20933024].
