Anti-NBR1

NBR1 protein is known for its encoding gene proximity to the BRCA1 tumor suppressor gene. N-terminal Phox and Bem1p (PB1) domains of NBR1 mediate its interaction with muscle specific titin kinase and scaffolding protein p62. NBR1 plays a role in autophagy by facilitating the autophagosomal degradation of ubiquitinated proteins independently and also in concert with p62. Protein function: Ubiquitin-binding autophagy adapter that participates in different processes including host defense or intracellular homeostasis (PubMed:33577621, PubMed:24692539). 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. In turn, activates the KEAP1-NRF2/NFE2L2 antioxidant pathway. Plays also non-autophagy role by mediating the shuttle of IL-12 to late endosome for subsequent secretion.
