CC -!- FUNCTION: Component of the PAF1 complex (PAF1C) which has multiple
CC functions during transcription by RNA polymerase II and is implicated
CC in regulation of development and maintenance of embryonic stem cell
CC pluripotency. PAF1C associates with RNA polymerase II through
CC interaction with POLR2A CTD non-phosphorylated and 'Ser-2'- and 'Ser-
CC 5'-phosphorylated forms and is involved in transcriptional elongation,
CC acting both independently and synergistically with TCEA1 and in
CC cooperation with the DSIF complex and HTATSF1. PAF1C is required for
CC transcription of Hox and Wnt target genes. PAF1C is involved in
CC hematopoiesis and stimulates transcriptional activity of KMT2A/MLL1.
CC PAF1C is involved in histone modifications such as ubiquitination of
CC histone H2B and methylation on histone H3 'Lys-4' (H3K4me3). PAF1C
CC recruits the RNF20/40 E3 ubiquitin-protein ligase complex and the E2
CC enzyme UBE2A or UBE2B to chromatin which mediate monoubiquitination of
CC 'Lys-120' of histone H2B (H2BK120ub1); UB2A/B-mediated H2B
CC ubiquitination is proposed to be coupled to transcription. PAF1C is
CC involved in mRNA 3' end formation probably through association with
CC cleavage and poly(A) factors. Connects PAF1C with the RNF20/40 E3
CC ubiquitin-protein ligase complex. Involved in polyadenylation of mRNA
CC precursors (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Component of the PAF1 complex, which consists of CDC73, PAF1,
CC LEO1, CTR9, RTF1 and WDR61 (By similarity). The PAF1 complex interacts
CC with PHF5A (By similarity). Interacts with POLR2A, TCEA1, TTC37,
CC KMT2A/MLL1, SUPT5H, RNF20 and RNF40. Interacts with UBE2E1 (By
CC similarity). {ECO:0000250|UniProtKB:Q8K2T8,
CC ECO:0000250|UniProtKB:Q8N7H5}.
CC -!- SUBCELLULAR LOCATION: Nucleus. Note=Punctuate distribution throughout
CC the nucleus except in nucleoli and the perinuclear chromatin.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the PAF1 family. {ECO:0000305}.
