The protein encoded by this gene was originally identified as an ovarian tumor antigen monitored in ovarian cancer. The encoded protein contains a B-box/coiled-coil motif, which is present in many genes with transformation potential. It functions as a specific autophagy receptor for the selective autophagic degradation of peroxisomes by forming intracellular inclusions with ubiquitylated autophagic substrates. This gene is located on a region of chromosome 17q21.1 that is in close proximity to the BRCA1 tumor suppressor gene. Alternative splicing of this gene results in multiple transcript variants.NBR1 (NBR1, Autophagy Cargo Receptor) is a Protein Coding gene. Diseases associated with NBR1 include Inclusion Body Myositis and Synucleinopathy. Among its related pathways are Mitophagy - animal. GO annotations related to this gene include ubiquitin binding and mitogen-activated protein kinase binding.
