Involved in ubiquitin-dependent protein catabolic process. Located in proteasome storage granule. Part of proteasome regulatory particle, lid subcomplex. Orthologous to human PSMD8 (proteasome 26S subunit, non-ATPase 8).
SGD Description
Subunit of the 19S regulatory particle of the 26S proteasome lid; synthetically lethal with RPT1, which is an ATPase component of the 19S regulatory particle; physically interacts with Nob1p and Rpn3p; protein abundance increases in response to DNA replication stress
