    ..Furthermore, both rhHR23 proteins function in a defined NER system reconstituted with purified proteins, indicating direct involvement of hHR23 proteins in the DNA repair reaction via interaction with XPC. ..

    ..These findings resolve the primary function of RAD23 in repair and reveal a novel DNA-damage-dependent regulation mechanism of DNA repair in eukaryotes, which may be part of a more global damage-response circuitry. ..

    ..Our findings reveal a scaffolding role of postsynaptic CaMKIIalpha in activity-dependent proteasome redistribution, which is commensurate with the great abundance of CaMKIIalpha in synapses. ..

    ..Based on our results we propose a model where ataxin-3 normally functions with its interactors to specify the cellular fate of ubiquitinated proteins. ..

    ..Here we show that contrary to prediction from this model, the effect of human Rad23A on the degradation of polyubiquitinated substrates catalyzed by purified proteasomes is exclusively inhibitory...

    ..These findings suggest that Vpr-proteasome interaction might counteract certain host restriction factor(s) to stimulate viral replication in non-dividing cells. ..
