WDR82 Peptide - N-Terminal Region Blocking Peptide

WDR82: a WD repeat-containing protein. A regulatory component of the histone H3K4 methylatransferase SET1 complex implicated in tethering this complex to transcriptional start sites of active genes. Facilitates histone H3K4 methylation via recruitment of the SETD1A or SETD1B to phospho-S5 in the C-terminal domain (CTD) of RNA polymerase II large subunit (POLR2A). Component of PTW/PP1 phosphatase complex, which plays a role in the control of chromatin structure and cell cycle progression during the transition from mitosis into interphase. Component of the SET1 complex, composed of at least the catalytic subunit (SETD1A or SETD1B), WDR5, WDR82, RBBP5, ASH2L/ASH2, CXXC1/CFP1, HCFC1 and DPY30. Component of the PTW/PP1 phosphatase complex, composed of PPP1R10/PNUTS, TOX4, WDR82, and PPP1CA, ¿B, or -C. Associated with multiple protein complexes including an RNA polymerase II complex, MLL3/MLL4 complex and a chaperonin-containing TCP1 complex. Interacts with CUL4B. Interacts with RBBP5 and SETD1B. Interacts with SETD1A (via RRM domain). Interacts with POLR2B. Interacts with hyperphosphorylated C-terminal domain (CTD) of RNA polymerase II large subunit (POLR2A). SETD1A enhances its interaction with POLR2A. Interacts with PPP1R10/PNUTS. Interacts with PPP1CA in the presence of PPP1R10/PNUTS.
