RT "5-Hydroxymethylcytosine plays a critical role in glioblastomagenesis by
RT recruiting the CHTOP-methylosome complex.";
RL Cell Rep. 9:48-60(2014).
CC -!- FUNCTION: Plays an important role in the ligand-dependent activation of
CC estrogen receptor target genes (By similarity). May play a role in the
CC silencing of fetal globin genes (PubMed:20688955). Recruits the 5FMC
CC complex to ZNF148, leading to desumoylation of ZNF148 and subsequent
CC transactivation of ZNF148 target genes (PubMed:22872859). Required for
CC the tumorigenicity of glioblastoma cells. Binds to 5-
CC hydroxymethylcytosine (5hmC) and associates with the methylosome
CC complex containing PRMT1, PRMT5, MEP50 and ERH. The CHTOP-methylosome
CC complex associated with 5hmC methylates H4R3 and transactivates genes
CC involved in glioblastomagenesis (PubMed:25284789).

CC -!- SUBUNIT: Interacts with PRMT1 and PRMT5 (PubMed:19858291,
CC PubMed:22872859). Interacts with the 5FMC complex; the interaction is
CC methylation-dependent. Interacts with FYTTD1, SET and PRC1 complex
CC members CBX4, RNF2 and PHC2; the interactions are methylation-
CC independent. Interacts with ZNF148 (PubMed:22872859). Interacts with
CC WDR77 and ERH (By similarity). {ECO:0000250|UniProtKB:Q9Y3Y2,
