It has been shown to be an E3 ubiquitin protein ligase that targets LIM domain binding 1 (LDB1/CLIM), and causes proteasome-dependent degradation of LDB1. This protein and LDB1 are co-repressors of LHX1/LIM-1, a homeodomain transcription factor. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Feb 2009]. * **UniProt Summary**: E3 ubiquitin-protein ligase. Acts as a negative coregulator for LIM homeodomain transcription factors by mediating the ubiquitination and subsequent degradation of LIM cofactors LDB1 and LDB2 and by mediating the recruitment the SIN3a/histone deacetylase corepressor complex. Ubiquitination and degradation of LIM cofactors LDB1 and LDB2 allows DNA-bound LIM homeodomain transcription factors to interact with other protein partners such as RLIM. Plays a role in telomere length-mediated growth suppression by mediating the ubiquitination and degradation of TERF1. By targeting ZFP42 for degradation, acts as an activator of random inactivation of X chromosome in the embryo, a stochastic process in which one X chromosome is inactivated to minimize sex- related dosage differences of X-encoded genes in somatic cells of female placental mammals. {ECO:0000269|PubMed:19164295, ECO:0000269|PubMed:19945382}. |zf-C3HC4| |zf-rbx1| |regulation of dosage compensation by inactivation of X chromosome| |random inactivation of X chromosome| |dosage compensation by inactivation of X chromosome| |dosage compensation| |transcriptional repressor complex| |negative regulation of DNA-binding transcription factor activity| |ubiquitin protein ligase activity| |regulation of gene expression, epigenetic| |transcription corepressor activity| |ubiquitin-protein transferase activity| |protein polyubiquitination| |regulation of DNA-binding transcription factor activity| |ubiquitin-dependent protein catabolic process| |modification-dependent protein catabolic process| |modification-dependent macromolecule catabolic process| |proteolysis involved in cellular protein catabolic process| |cellular protein catabolic process| |protein catabolic process| |protein ubiquitination| |protein modification by small protein conjugation| |negative regulation of transcription by RNA polymerase II| |cellular macromolecule catabolic process| |protein modification by small protein conjugation or removal| |macromolecule catabolic process| |organonitrogen compound catabolic process| |negative regulation of molecular function| |negative regulation of transcription, DNA-templated| |negative regulation of nucleic acid-templated transcription| |negative regulation of RNA biosynthetic process| |proteolysis| |negative regulation of RNA metabolic process| |negative regulation of cellular macromolecule biosynthetic process| |negative regulation of nucleobase-containing compound metabolic process| |negative regulation of macromolecule biosynthetic process| |negative regulation of cellular biosynthetic process| |negative regulation of biosynthetic process| |negative regulation of gene expression| |organic substance catabolic process| |cellular catabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp415|Trichostatin-A 0.06μM R07 exp415]]|-2.06| |[[:results:exp320|ABT-702 5μM plus CoCl2 18μM R07 exp320]]|-1.76| |[[:results:exp264|Arsenate 40μM R06 exp264]]|2.12| No correlation found to any other genes in chemogenomics.
