NBR1 (human)

NBR1 Acts probably as a receptor for selective autophagosomal degradation of ubiquitinated targets. Homooligomer and heterooligomer. Interacts with TRIM55. Interacts with SQSTM1, titin/TTN, RNF29, USP8, SQSTM1, MAP1LC3A, MAP1LC3B, MAP1LC3C, GABARAP, GABARAPL1 and GABARAPL2. Binds to ubiquitin and ubiquitinated proteins. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
