What is the function of this protein?
Transcriptional coregulator (By similarity).  Involved in control of the cell cycle (PubMed:9087427).  Also antagonizes transactivation by ZBTB17 and GABP2; represses ZBTB17 activation of the p15(INK4b) promoter and inhibits its ability to recruit p300 (By similarity).  Coactivator for EGR2 and GABP2 (By similarity).  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 (By similarity).  As part of the NSL complex it may be involved in acetylation of nucleosomal histone H4 on several lysine residues (By similarity).  Recruits KMT2E to E2F1 responsive promoters promoting transcriptional activation and thereby facilitates G1 to S phase transition (By similarity).  Modulates expression of homeobox protein PDX1, perhaps acting in concert with transcription factor E2F1, thereby regulating pancreatic beta-cell growth and glucose-stimulated insulin secretion (By similarity).  May negatively modulate transcriptional activity of FOXO3 (By similarity).
What are the official names of this protein?
Host cell factor 1, HCF, HCF-1, C1 factor, VCAF, VP16 accessory protein.
What are the subcellular locations of this protein?
Cytoplasm. Nucleus. Note=HCFC1R1 modulates its subcellular localization and overexpression of HCFC1R1 leads to accumulation of HCFC1 in the cytoplasm. Non-processed HCFC1 associates with chromatin. Colocalizes with CREB3 and CANX in the ER.
