Transcription factor that activates the expression of the EIF2S1 (EIF2-alpha) gene. Links the transcriptional modulation of key metabolic genes to cellular growth and development. Implicated in the control of nuclear genes required for respiration, heme biosynthesis, and mitochondrial DNA transcription and replication. Source: Recombinant protein corresponding to aa1-503 from mouse Nrf1, fused to His-SUMO-Tag at N-terminal, expressed in E. coli.
