Human Gene USP4 (uc003cwq.2) Description and Page Index
  Description: Homo sapiens ubiquitin specific peptidase 4 (proto-oncogene) (USP4), transcript variant 1, mRNA.
RefSeq Summary (NM_003363): The protein encoded by this gene is a protease that deubiquitinates target proteins such as ADORA2A and TRIM21. The encoded protein shuttles between the nucleus and cytoplasm and is involved in maintaining operational fidelity in the endoplasmic reticulum. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011].

  ID: UBP4_HUMAN
DESCRIPTION: RecName: Full=Ubiquitin carboxyl-terminal hydrolase 4; EC=3.4.19.12; AltName: Full=Deubiquitinating enzyme 4; AltName: Full=Ubiquitin thioesterase 4; AltName: Full=Ubiquitin-specific-processing protease 4; AltName: Full=Ubiquitous nuclear protein homolog;
FUNCTION: Hydrolase that deubiquitinates target proteins such as the receptor ADORA2A, PDPK1 and TRIM21. Deubiquitination of ADORA2A increases the amount of functional receptor at the cell surface. Plays a role in the regulation of quality control in the ER.
CATALYTIC ACTIVITY: Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C- terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal).
SUBUNIT: Interacts with RB1 (both dephosphorylated and hypophosphorylated forms). Interacts with ADORA2A (via cytoplasmic C-terminus); the interaction is direct. Interacts with RB1, RBL1 and RBL2.
INTERACTION: P29274:ADORA2A; NbExp=4; IntAct=EBI-723290, EBI-2902702; P19474:TRIM21; NbExp=3; IntAct=EBI-723305, EBI-81290;
SUBCELLULAR LOCATION: Cytoplasm (By similarity). Nucleus (By similarity). Note=Shuttles between the nucleus and cytoplasm. Exported to the cytoplasm in a CRM1-dependent manner and recycled back to the nucleus via the importin alpha/beta heterodimeric import receptor. The relative amounts found in the nucleus and cytoplasm vary according to the cell type (By similarity).
TISSUE SPECIFICITY: Overexpressed in small cell tumors and adenocarcinomas of the lung compared to wild-type lung (at protein level). Expressed in the hippocampal neurons.
DOMAIN: The Ubiquitin-like domain 2 inserts into the catalytic domain and competes with the ubiquitin substrate, partially inhibiting DUB activity.
PTM: Monoubiquitinated by TRIM21. Ubiquitination does not lead to its proteasomal degradation. Autodeubiquitinated.
SIMILARITY: Belongs to the peptidase C19 family. USP4 subfamily.
SIMILARITY: Contains 1 DUSP domain.
SIMILARITY: Contains 2 ubiquitin-like domains.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
