What are RNA polymerase II 's transcription factors and promoters? what's common component of these promoters?

General transcription factors (called TFIIX) to initiate transcription.the promoters frequently have a short conserved sequence Py2CAPy5 (the initiator Inr) at the start point. -The TATA box is a common component of RNA polymerase II promoters and consists of an A-T-rich octamer located ~25 bp upstream of the start point.
