Enables

This protein enables 4 target(s):

TargetCategoryDefinition
protein bindingmolecular functionBinding to a protein. [GOC:go_curators]
methyl-CpG bindingmolecular functionBinding to a methylated cytosine/guanine dinucleotide. [GOC:jl, PMID:11746232]
nuclear receptor coactivator activitymolecular functionA transcription coactivator activity that activates or increases the transcription of specific gene sets via binding to a DNA-bound nuclear receptor, either on its own or as part of a complex. Coactivators often act by altering chromatin structure and modifications. For example, one class of transcription coregulators modifies chromatin structure through covalent modification of histones. A second class remodels the conformation of chromatin in an ATP-dependent fashion. A third class modulates interactions of DNA-bound DNA-binding transcription factors with other transcription coregulators. A fourth class of coactivator activity is the bridging of a DNA-binding transcription factor to the general (basal) transcription machinery. The Mediator complex, which bridges sequence-specific DNA binding transcription factors and RNA polymerase, is also a transcription coactivator. [GOC:dph, GOC:tb]
ubiquitin-like ligase-substrate adaptor activitymolecular functionThe binding activity of a molecule that brings together a ubiquitin-like ligase (including ubiquitin ligase and UFM1 ligase) and its substrate. Usually mediated by F-box BTB/POZ domain proteins. [PMID:24658274]

Located In

This protein is located in 5 target(s):

TargetCategoryDefinition
nucleuscellular componentA membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. [GOC:go_curators]
nucleoplasmcellular componentThat part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653]
cytoplasmcellular componentThe contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684]
Golgi apparatuscellular componentA membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways. [ISBN:0198506732]
cytosolcellular componentThe part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl]

Part Of

This protein is part of 2 target(s):

TargetCategoryDefinition
methylosomecellular componentA large (20 S) protein complex that possesses protein arginine methyltransferase activity and modifies specific arginines to dimethylarginines in the arginine- and glycine-rich domains of several spliceosomal Sm proteins, thereby targeting these proteins to the survival of motor neurons (SMN) complex for assembly into small nuclear ribonucleoprotein (snRNP) core particles. Proteins found in the methylosome include the methyltransferase JBP1 (PRMT5), pICln (CLNS1A), MEP50 (WDR77), and unmethylated forms of SM proteins that have RG domains. [PMID:11713266, PMID:11756452]
Cul4B-RING E3 ubiquitin ligase complexcellular componentA ubiquitin ligase complex in which a cullin from the Cul4B subfamily and a RING domain protein form the catalytic core; substrate specificity is conferred by unknown subunits. [PMID:15571813, PMID:15688063]
