OTUD7B

OTUD7B (OTU Deubiquitinase 7B) is a Protein Coding gene. Among its related pathways are Metabolism of proteins and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include cysteine-type peptidase activity and obsolete ubiquitin thiolesterase activity. An important paralog of this gene is OTUD7A.

OTU Deubiquitinase 7B

Negative regulator of the non-canonical NF-kappa-B pathway that acts by mediating deubiquitination of TRAF3, an inhibitor of the NF-kappa-B pathway, thereby acting as a negative regulator of B-cell responses. In response to non-canonical NF-kappa-B stimuli, deubiquitinates 'Lys-48'-linked polyubiquitin chains of TRAF3, preventing TRAF3 proteolysis and over-activation of non-canonical NF-kappa-B. Negatively regulates mucosal immunity against infections (By similarity).
Deubiquitinates ZAP70, and thereby regulates T cell receptor (TCR) signaling that leads to the activation of NF-kappa-B (PubMed:26903241).
Plays a role in T cell homeostasis and is required for normal T cell responses, including production of IFNG and IL2 (By similarity).
Mediates deubiquitination of EGFR (PubMed:22179831).
Has deubiquitinating activity toward 'Lys-11', 'Lys-48' and 'Lys-63'-linked polyubiquitin chains (PubMed:27732584).
Has a much higher catalytic rate with 'Lys-11'-linked polyubiquitin chains (in vitro); however the physiological significance of these data are unsure (PubMed:27732584).
Hydrolyzes both linear and branched forms of polyubiquitin.
