[[http://www.uniprot.org/uniprot/PSD4_HUMAN PSD4_HUMAN]] Guanine nucleotide exchange factor for ARF6 and ARL14/ARF7. Through ARL14 activation, controls the movement of MHC class II-containing vesicles along the actin cytoskeleton in dendritic cells. Involved in membrane recycling. Interacts with several phosphatidylinositol phosphate species, including phosphatidylinositol 3,4-bisphosphate, phosphatidylinositol 3,5-bisphosphate and phosphatidylinositol 4,5-bisphosphate.<ref>PMID:12082148</ref> <ref>PMID:21458045</ref> [[http://www.uniprot.org/uniprot/RD23A_HUMAN RD23A_HUMAN]] 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.<ref>PMID:9372924</ref> <ref>PMID:14621999</ref> <ref>PMID:12643283</ref> <ref>PMID:15321727</ref> <ref>PMID:20614012</ref> 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.
