Active Recombinant Human POLR2C, His-tagged

• Cat.No.: POLR2C-8462H
• Product Overview: Recombinant Human POLR2C, fused with His tag, was expressed in E. coli.

Specification

• Description: hRPB3 (p33) is a highly conserved subunit shared by all three RNA polymerases. It has been shown to be in close contact to promoter DNA when pol II is recruited into the preinitiation complex . RPB3 has also been implicated in direct protein-protein contacts with transcription factor IIB , Rap30 subunit of transcription factor IIF , and gene-specific modulator proteins, such as the hepatitis B virus transactivator protein X or an inhibitor of pol II, RMP (RPB3-mediating protein). Therefore, RPB3 is facilitating the communication between the pol II core and a variety of basal and gene-specific transcription factors. In the pol II complex, RPB3 interacts with RPB5 and the RPB3–RPB5 interaction is intensified in the presence of three subunits, RPB7, RPB8 and RPB11 . RPB3 also makes direct contacts with both RPB1 and RPB2, the two large subunits of the polymerase complex.
