Protein: RNA polymerase sigma factor sigC (Sigma factor C) (Sigma-C) (RNA polymerase sigma factor sig3) (Atsig3) (Sigma factor 3) (O24621)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Sigma factors are initiation factors that promote the attachment of plastid-encoded RNA polymerase (PEP) to specific initiation sites and are then released.
Subcellular location: Plastid, chloroplast {ECO:0000269|PubMed:10555304, ECO:0000269|PubMed:12602869, ECO:0000269|PubMed:9405719}. Note=Seems attached to membranes. {ECO:0000269|PubMed:12602869}.
