研究背景
Deubiquitinating enzyme that removes conjugated ubiquitin from target proteins. Deubiquitinates PDPK1. Deubiquitinates TRIM21. Deubiquitinates receptor ADORA2A which increases the amount of functional receptor at the cell surface. May regulate mRNA splicing through deubiquitination of the U4 spliceosomal protein PRPF3. This may prevent its recognition by the U5 component PRPF8 thereby destabilizing interactions within the U4/U6.U5 snRNP. May also play a role in the regulation of quality control in the ER.
Monoubiquitinated by TRIM21. Ubiquitination does not lead to its proteasomal degradation. Autodeubiquitinated.
Cytoplasm. Nucleus.
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.
Overexpressed in small cell tumors and adenocarcinomas of the lung compared to wild-type lung (at protein level). Expressed in the hippocampal neurons.
Interacts with RB1 (both dephosphorylated and hypophosphorylated forms). Interacts with RBL1 and RBL2 (By similarity). Interacts with ADORA2A (via cytoplasmic C-terminus); the interaction is direct. Interacts with SART3; recruits USP4 to its substrate PRPF3.
The DUSP and ubiquitin-like 1 domains promote ubiquitin release and thus enhance USB4 catalytic activity. However, these domains do not bind ubiquitin.
Belongs to the peptidase C19 family. USP4 subfamily.
