Enables K48-linked polyubiquitin modification-dependent protein binding activity and protein phosphatase regulator activity. Involved in several processes, including macroautophagy; proteasomal protein catabolic process; and sister chromatid biorientation. Located in cytosol and nucleus. Orthologous to several human genes including UBXN2B (UBX domain protein 2B).
SGD Description
Substrate adaptor for Cdc48p; ubiquitin regulatory X (UBX) and Ub-associated (UBA) domain-containing protein that acts as a substrate recruiting cofactor; K48-specific Ub chain binding protein involved in ER-associated degradation (ERAD); positively regulates Glc7p protein phosphatase activity to promote growth and mitotic progression in complex with Cdc48p; regulated by nuclear Ub-dependent degradation (INMAD pathway) independent of the Asi and Doa10 complexes; homolog of human p47 (NSFL1C)
