NBR1 (Next to BRCA1 gene 1) is a protein which is ubiquitously expressed and highly conserved in eukaryotic organisms. NBR1 is implicated in TITIN kinase signaling in muscles and mitigates FGFR signaling through NBR1- SPRED2 interactions. Animals expressing truncated NBR1 lacking the C-terminal region has been shown to develop excessive bone mass due to increased activity of osteoblasts, suggesting NBR1's role in modulating bone metabolism in vivo. NBR1 functions as a negative regulator of p38 MAPK activity and has also been discovered as a binding partner of ATG8 family members including LC3, GABARAP, GABARAP-like 1/GABARAPL1, and GATE-16/GABARAPL2 in mammalian cells wherein these proteins are known to play essential role in formation of autophagosomes. Moreover, NBR1 interacts with ubiquitin/ubiquitinated proteins via ubiquitin-associated (UBA) domain and also interacts with TRIM55, SQSTM1, RNF29, USP8 etc. Based on these properties, it has been proposed that NBR1 functions as a cargo adapter for autophagic degradation of ubiquitinated substrates in a similar way to p62.
