RAD23A, Recombinant, Human, aa1-363, His-Tag (UV Excision Repair Protein RAD23 Homolog A)

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. 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.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. Involved in vpr-dependent replication of HIV-1 in non-proliferating cells and primary macrophages. Required for the association of HIV-1 vpr with the host proteasome. Source: Recombinant protein corresponding to aa1-363 from human RAD23A, fused to His-Tag at N-terminal, expressed in Yeast.
