NBR1

Next to BRCA1 gene 1 protein; Isoform 2 of Next to BRCA1 gene 1 protein

Ubiquitin-binding autophagy adapter that participates in different processes including host defense or intracellular homeostasis (PubMed:24692539, PubMed:33577621). Possesses a double function during the selective autophagy by acting as a shuttle bringing ubiquitinated proteins to autophagosomes and also by participating in the formation of protein aggregates (PubMed:24879152, PubMed:34471133). Plays a role in the regulation of the innate immune response by modulating type I interferon production and targeting ubiquitinated IRF3 for autophagic degradation (PubMed:35914352). In response to oxidative stress, promotes an increase in SQSTM1 levels, phosphorylation, and body formation by preventing its autophagic degradation (By similarity). In turn, activates the KEAP1-NRF2/NFE2L2 antioxidant pathway (By similarity). Plays also non-autophagy role by mediating the shuttle of IL-12 to late endosome for subsequent secretion (By similarity).
