CC -!- FUNCTION: Tumor suppressor probably involved in transcriptional and
CC post-transcriptional control pathways. May be involved in cell cycle
CC progression through the regulation of cyclin D1/PRAD1 expression.
CC Component of the PAF1 complex (PAF1C) which has multiple functions
CC during transcription by RNA polymerase II and is implicated in
CC 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 cleavage and
CC polyadenylation specificity factor (CPSF) complex and the cleavage
CC stimulation factor (CSTF) complex, and with Wnt signaling. Involved in
CC polyadenylation of mRNA 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. Within the PAF1 complex interacts directly with PHF5A (By
CC similarity). Interacts with POLR2A, CPSF1, CPSF4, CSTF2, KMT2A/MLL1 and
CC CTNNB1. Interacts with a Set1-like complex that has histone
CC methyltransferase activity and methylates histone H3. Found in a
CC complex with BCL9L or BCL9, CDC73, CTNNB1 and PYGO1 indicative for the
CC participation in a nuclear Wnt signaling complex. Interacts with PTPN11
CC (By similarity). Interacts with SETD5 (By similarity).
CC {ECO:0000250|UniProtKB:Q6P1J9, ECO:0000250|UniProtKB:Q8JZM7}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- PTM: Phosphorylated. Dephosphorylated by PTPN11.
CC {ECO:0000250|UniProtKB:Q6P1J9}.
CC -!- SIMILARITY: Belongs to the CDC73 family. {ECO:0000305}.
