Also known as
RNA POLYMERASE SIGMA-SUBUNIT; RNApolymerase sigma-subunit C; SIG3; SIGMA FACTOR 3
Summary
Encodes a sigma-like transcription factor, Sigma 3 (SIG3 or SIGC). As a subunit of chloroplast RNA polymerase, SIG3 confers the ability to recognize promoter sequences on the core enzyme. SIG3 transcribes specifically the psbN gene in plastids.
