Background Information
DNA-directed RNA polymerase II subunit RPB1 (EC 2.7.7.6; EC 2.7.7.48; UniProt P24928; also known as DNA-directed RNA polymerase II subunit A, DNA-directed RNA polymerase II subunit RPB1, DNA-directed RNA polymerase III largest subunit, hRPB220, hsRPB1, RNA polymerase II subunit B1, RPBh1, RpIILS) is encoded by the POLR2A (also known as POLR2, POLRA, RPB1, RPO2, RPOL2) gene (Gene ID 5430) in human. RNA polymerase II (Pol II) is a 550 kDa, multi-subunit enzyme responsible for the transcription of protein-coding genes. Transcription initiation requires recruitment of the complete transcription machinery to a promoter via solicitation by activators and chromatin remodeling factors. Pol II can coordinate 10 to 14 subunits. This complex interacts with the promoter regions of genes and a variety of elements and transcription factors. The DNA binding domain of the polymerase is a groove where TFIIB orients the DNA for unwinding and transcription.
