Antibodies recognize recombinant RAD23b and RAD23c proteins equally well but do not recognize DSK2a/b orDDI1 based on immunoblot analyses of corresponding mutants Farmer et al. (2010).
RAD23c(ubiquitin receptor RAD23c) binds to and may select ubiquitin couplets for destruction. Preference for multiple ubiquitin chains over single ubiquitin chains, with binding affinity for 'Lys-48' linked ubiquitin chains. As a ubiquitin receptor, it binds to the 26S proteasome docking subunit RPN10 and indirectly recognizes ubiquitin /26S proteasoma-mediated proteolysis (UPP) as a ubiquitin substrate. The RAD23 protein plays an important role in plant cell cycle, morphology and fertility by delivering UPS (ubiquitin/26S proteasome system) substrates to the 26S proteasome. Alias :AtRAD23c, putative DNA repair protein RAD23-3, RAD23-like protein 3,AtRAD23-3.
