Predicted to enable polyubiquitin modification-dependent protein binding activity; proteasome binding activity; and ubiquitin binding activity. Predicted to be involved in nucleotide-excision repair and proteasome-mediated ubiquitin-dependent protein catabolic process. Located in cytoplasm and nucleus. Is expressed in adult head and organism. Orthologous to several human genes including RAD23A (RAD23 homolog A, nucleotide excision repair protein).
FB Description
Rad23 (Rad23) encodes an evolutionarily conserved member of the proteasome-associated proteins. It acts as a shuttle -or bridge- protein helping ubiquitinated proteins to interact with the proteasome, which in turn regulates their turnover.
