Verification Images

  • Experimental Validation Results for PAF1 Antibody (YA2505)
    Western blot analysis was performed on protein extracts (25 μg) from HeLa (lane 1), U87 (lane 2), Jurkat (lane 3), and HepG2 (lane 4) using PAF1 antibody. Proteins were transferred onto a 0.45 μm PVDF membrane using the Trans-Blot® Turbo™ system for 13 min. The membrane was then blocked with 5% nonfat milk in TBST (HY-K1025) for 1 h at room temperature. The primary antibody (1:1000) and loading control antibody GAPDH Antibody (HRP) (HY-P80954A) (1:5000) were diluted in 5% nonfat milk in TBST and incubated with the membrane overnight at 4°C. After washing, the membrane of primary antibody was incubated with HRP-conjugated goat anti-rabbit/mouse IgG secondary antibody (HY-P8001/HY-P8004) (1:5000) diluted in 5% nonfat milk in TBST for 1 h at room temperature. Protein bands were visualized using an Ultra High Sensitivity ECL detection kit (HY-K1005).

Background

  • Function

    PAF1 component of the PAF1 complex (PAF1C) which has multiple functions during transcription by RNA polymerase II and is implicated in regulation of development and maintenance of embryonic stem cell pluripotency. PAF1C associates with RNA polymerase II through interaction with POLR2A CTD non-phosphorylated and 'Ser-2'- and 'Ser-5'-phosphorylated forms and is involved in transcriptional elongation, acting both independently and synergistically with TCEA1 and in cooperation with the DSIF complex and HTATSF1. PAF1C is required for transcription of Hox and Wnt target genes. PAF1C is involved in hematopoiesis and stimulates transcriptional activity of KMT2A/MLL1; it promotes leukemogenesis through association with KMT2A/MLL1-rearranged oncoproteins, such as KMT2A/MLL1-MLLT3/AF9 and KMT2A/MLL1-MLLT1/ENL. PAF1C is involved in histone modifications such as ubiquitination of histone H2B and methylation on histone H3 'Lys-4' (H3K4me3). PAF1C recruits the RNF20/40 E3 ubiquitin-protein ligase complex and the E2 enzyme UBE2A or UBE2B to chromatin which mediate monoubiquitination of 'Lys-120' of histone H2B (H2BK120ub1); UB2A/B-mediated H2B ubiquitination is proposed to be coupled to transcription. PAF1C is involved in mRNA 3' end formation probably through association with cleavage and poly(A) factors. In case of infection by influenza A strain H3N2, PAF1C associates with viral NS1 protein, thereby regulating gene transcription. Connects PAF1C with the RNF20/40 E3 ubiquitin-protein ligase complex. Involved in polyadenylation of mRNA precursors. Has oncogenic activity in vivo and in vitro

  • Subunit

    Component of the PAF1 complex, which consists of CDC73, PAF1, LEO1, CTR9, RTF1 and SKIC8 (PubMed:19952111, PubMed:20178742). The PAF1 complex interacts with PHF5A (By similarity). Interacts with POLR2A, TCEA1, SKIC3, KMT2A/MLL1, SUPT5H, RNF20 and RNF40 (PubMed:15923622, PubMed:16024656, PubMed:16491129, PubMed:19410543, PubMed:19952111, PubMed:20178742, PubMed:20541477). Interacts with UBE2E1 (PubMed:16307923). Interacts with PINT87aa which is encoded by the circular form of the long non-coding RNA LINC-PINT; the interaction enhances the binding of the PAF1 complex to target gene promoters and may anchor the complex on target gene promoters, sequentially pausing RNA polymerase II-induced mRNA elongation (PubMed:30367041)
