DESCRIPTION

Also known as UBP20_HUMAN, USP20, KIAA1003, LSFR3A, VDU2. Deubiquitinating enzyme involved in beta-2 adrenergic receptor (ADRB2) recycling. Acts as a regulator of G-protein coupled receptor (GPCR) signaling by mediating the deubiquitination beta-2 adrenergic receptor (ADRB2). Plays a central role in ADRB2 recycling and resensitization after prolonged agonist stimulation by constitutively binding ADRB2, mediating deubiquitination of ADRB2 and inhibiting lysosomal trafficking of ADRB2. Upon dissociation, it is probably transferred to the translocated beta-arrestins, possibly leading to beta-arrestins deubiquitination and disengagement from ADRB2. This suggests the existence of a dynamic exchange between the ADRB2 and beta-arrestins. Deubiquitinates DIO2, thereby regulating thyroid hormone regulation. Deubiquitinates HIF1A, leading to stabilize HIF1A and enhance HIF1A-mediated activity. Mediates deubiquitination of both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains. Interacts with VHL, leading to its ubiquitination and subsequent degradation (PubMed:12056827). Interacts with CCP110 (PubMed:23486064). Interacts with DIO2 (PubMed:12865408). Interacts with HIF1A (PubMed:15776016). Interacts with ADRB2 (PubMed:19424180, PubMed:23166351).
