UniProt functional annotation for B5DF11



	UniProt functional annotation for B5DF11

UniProt code: B5DF11.

Organism: Rattus norvegicus (Rat).

Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus.

Function: Involved in protein degradation via the ubiquitin-proteasome system. May act by anchoring ubiquitinated proteins to the proteasome. Plays a role in ubiquitin-mediated protein degradation during muscle atrophy. Plays a role in the regulation of NF-kappa-B activation and apoptosis. Inhibits NF-kappa-B activation triggered by overexpression of RIPK1 and TRAF6 but not of RELA. Inhibits also tumor necrosis factor (TNF), IL-1 and TLR4-induced NF-kappa-B activation in a dose-dependent manner. Overexpression sensitizes cells to TNF-induced apoptosis. Is a potent inhibitory factor for osteoclast differentiation (By similarity). {ECO:0000250}.

Subunit: Homooligomer and/or heterooligomer. Interacts (via A20-type domain) with IKBKG and RIPK1 and with TRAF6 (via AN1-type domain) (By similarity). Interacts with ubiquitin and polyubiquitinated proteins. Identified in a heterotrimeric complex with ubiquitin and SQSTM1, where ZFAND5 and SQSTM1 both interact with the same ubiquitin molecule. {ECO:0000250, ECO:0000269|PubMed:21923101}.

Subcellular location: Cytoplasm {ECO:0000269|PubMed:21923101}.

Domain: The A20-type zinc finger directly binds polyubiquitin chains and associates with the 26S proteasome. The zinc-finger A20-type domain is essential for inhibition of NF-kappa-B activation (By similarity). {ECO:0000250}.
