DESCRIPTION

Also known as HCFC1_HUMAN, HCFC1, HCF1, HFC1. Involved in control of the cell cycle (PubMed:10629049, PubMed:10779346, PubMed:15190068, PubMed:16624878, PubMed:23629655). Also antagonizes transactivation by ZBTB17 and GABP2; represses ZBTB17 activation of the p15(INK4b) promoter and inhibits its ability to recruit p300 (PubMed:10675337, PubMed:12244100). Coactivator for EGR2 and GABP2 (PubMed:12244100, PubMed:14532282). Tethers the chromatin modifying Set1/Ash2 histone H3 'Lys-4' methyltransferase (H3K4me) and Sin3 histone deacetylase (HDAC) complexes (involved in the activation and repression of transcription, respectively) together (PubMed:12670868). Component of a THAP1/THAP3-HCFC1-OGT complex that is required for the regulation of the transcriptional activity of RRM1 (PubMed:20200153). As part of the NSL complex it may be involved in acetylation of nucleosomal histone H4 on several lysine residues (PubMed:20018852). Recruits KMT2E/MLL5 to E2F1 responsive promoters promoting transcriptional activation and thereby facilitates G1 to S phase transition (PubMed:23629655)., (Microbial infection) In case of human herpes simplex virus (HSV) infection, HCFC1 forms a multiprotein-DNA complex with the viral transactivator protein VP16 and POU2F1 thereby enabling the transcription of the viral immediate early genes. Composed predominantly of six polypeptides ranging from 110 to 150 kDa and a minor 300 kDa polypeptide (PubMed:10920196). The majority of N- and C-terminal cleavage products remain tightly, albeit non-covalently, associated (PubMed:10920196). Interacts with POU2F1, CREB3, ZBTB17, EGR2, E2F4, CREBZF, SP1, GABP2, Sin3 HDAC complex (SIN3A, HDAC1, HDAC2, SUDS3), SAP30, SIN3B and FHL2 (PubMed:9271389, PubMed:9389645, PubMed:10675337, PubMed:10976766, PubMed:10629049, PubMed:10871379, PubMed:10984507, PubMed:12244100, PubMed:14532282, PubMed:12670868, PubMed:15705566, PubMed:16624878). Component of a MLL1 complex, composed of at least the core components KMT2A/MLL1, ASH2L, HCFC1, WDR5 and RBBP5, as well as the facultative components BAP18, CHD8, DPY30, E2F6, HCFC2, HSP70, INO80C, KANSL1, LAS1L, MAX, MCRS1, MEN1, MGA, KAT8, PELP1, PHF20, PRP31, RING2, RUVBL1, RUVBL2, SENP3, TAF1, TAF4, TAF6, TAF7, TAF9 and TEX10 (PubMed:15199122, PubMed:15960975). Component of a THAP1/THAP3-HCFC1-OGT complex that is required for the regulation of the transcriptional activity of RRM1 (PubMed:20200153). Interacts directly with THAP3 (via its HBM) (PubMed:20200153). Interacts (via the Kelch-repeat domain) with THAP1 (via the HBM); the interaction recruits HCHC1 to the RRM1 (PubMed:20200153). Interacts directly with OGT; the interaction, which requires the HCFC1 cleavage site domain, glycosylates and promotes the proteolytic processing of HCFC1, retains OGT in the nucleus and impacts the expression of herpes simplex virus immediate early viral genes (PubMed:12670868, PubMed:21285374, PubMed:23353889). Component of the SET1 complex, at least composed of the catalytic subunit (SETD1A or SETD1B), WDR5, WDR82, RBBP5, ASH2L, CXXC1, HCFC1 and DPY30 (PubMed:17998332, PubMed:18838538). Component of the NSL complex at least composed of MOF/KAT8, KANSL1, KANSL2, KANSL3, MCRS1, PHF20, OGT1/OGT, WDR5 and HCFC1 (PubMed:20018852). Component of a complex at least composed of ZNF335, HCFC1, CCAR2, EMSY, MKI67, RBBP5, ASH2L and WDR5; the complex is formed as a result of interactions between components of a nuclear receptor-mediated transcription complex and a histone methylation complex (PubMed:19131338). Within the complex interacts with ZNF335 (PubMed:19131338). Interacts with TET2 and TET3 (PubMed:23353889). Interacts with HCFC1R1 (PubMed:12235138). Interacts with THAP11 (By similarity). Interacts (via Kelch domain) with KMT2E/MLL5 isoform 3 (via HBM motif) (PubMed:23629655). Interacts with E2F1 (PubMed:23629655).

Also known as HCFC1_HUMAN, HCFC1, HCF1, HFC1. Involved in control of the cell cycle (PubMed:10629049, PubMed:10779346, PubMed:15190068, PubMed:16624878, PubMed:23629655). Also antagonizes trans ...
