Protein Structure
UniProt Annotation
Function Multiubiquitin chain receptor involved in modulation of proteasomal degradation. Binds to 'Lys-48'-linked polyubiquitin chains in a length-dependent manner and with a lower affinity to 'Lys-63'-linked polyubiquitin chains. Proposed to be capable to bind simultaneously to the 26S proteasome and to polyubiquitinated substrates and to deliver ubiquitinated proteins to the proteasome (By similarity). {ECO:0000250}.Involved in nucleotide excision repair and is thought to be functional equivalent for Rad23b in global genome nucleotide excision repair (GG-NER) by association with Xpc. In vitro, the XPC:RAD23A dimer has NER activity. Can stabilize Xpc. Reported differences to Rad23b in regard to NER activity and Xpc stabilization are probably due to differences in expression levels with Rad23a being much less expressed than Rad23b. {ECO:0000269PubMed:12815074, ECO:0000269PubMed:15336624}.
