Description:
A chloroplast RNA polymerase sigma factor is encoded by a nuclear gene, sigA, in the red alga Cyanidium caldarium RK-1. The encoded protein functions as an RNA polymerase sigma factor in vitro and it is localized to the chloroplast in vivo. SigA shows high sequence similarity to the sigma factors of cyanobacteria, which is indicative of the ancestral endosymbiotic event and subsequent transfer of the sigA gene to the nuclear genome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tanaka, K -- Oikawa, K -- Ohta, N -- Kuroiwa, H -- Kuroiwa, T -- Takahashi, H -- New York, N.Y. -- Science. 1996 Jun 28;272(5270):1932-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Molecular and Cellular Biosciences, University of Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8658165" target="_blank"〉PubMed〈/a〉
