Activated RNA polymerase II transcriptional coactivator p15 also known as positive cofactor 4 (PC4) or SUB1 homolog is a protein that in humans is encoded by the SUB1 gene.^[5]^[6]^[7] The human SUB1 gene^[7] is named after an orthologous gene in yeast.^[8]

SUB1 is induced by oxidative stress, and is involved in coordinating cellular responses to DNA strand breaks that arise after oxidative stress.Yu L, Ma H, Ji X, Volkert MR (January 2016). "The Sub1 nuclear protein protects DNA from oxidative damage". Molecular and Cellular Biochemistry. 412 (1–2): 165–171. doi:10.1007/s11010-015-2621-x. PMC 5064834. PMID 26708217. Yeast SUB1 has structural and functional similarities to human alpha-synuclein, a protein that has an important role in Parkinson’s disease.Schaser AJ, Osterberg VR, Dent SE, Stackhouse TL, Wakeham CM, Boutros SW, et al. (July 2019). "Alpha-synuclein is a DNA binding protein that modulates DNA repair with implications for Lewy body disorders". Scientific Reports. 9 (1): 10919. doi:10.1038/s41598-019-47227-z. PMC 6662836. PMID 31358782. Like SUB1, alpha-synuclein functions in regulating DNA repair including repair of DNA double-strand breaks.

Interactions

SUB1 has been shown to interact with CSTF2.^[9]
