Target Background

Function
Essential protein. Sigma factors are initiation factors that promote the attachment of plastid-encoded RNA polymerase (PEP) to specific initiation sites and are then released. Controls the transcription of the psaA gene and thus modulates photosystem stoichiometry. Thereby maintains a harmonious electron flow and photosynthetic efficiency.
Gene References into Functions
  1. SIG1 specifically binds to newly identified target promoters as well as to a set of promoters of genes. PMID: 23202891
  2. revealed an enhanced phosphorylation of SIG1 under oxidative conditions of plastoquinone in a form associated with the molecular mass of the holoenzyme. PMID: 20498041
  3. Red light induces transcription of SIG1 very strongly, whereas blue light induces transcription of both SIG1 and SIG5. PMID: 18532976
Subcellular Location
Plastid, chloroplast.
Protein Families
Sigma-70 factor family
Tissue Specificity
Highly expressed in leaves, and to a lesser extent in roots. Expressed in old seedlings (8 days), cotyledons, hypocotyls, leaves, sepals and siliques.
