MPR1, proteasome regulatory particle lid subunit RPN11, L000002976, L000002965, YFR004W
Metalloprotease subunit of 19S regulatory particle; part of 26S proteasome lid; couples the deubiquitination and degradation of proteasome substrates; involved, independent of catalytic activity, in fission of mitochondria and peroxisomes; protein abundance increases in response to DNA replication stress

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Publication

The Sts1 nuclear import adapter uses a non-canonical bipartite nuclear localization signal and is directly degraded by the proteasome.

Budenholzer L, Breckel C, Hickey CM, Hochstrasser M

The proteasome is an essential regulator of protein homeostasis. In yeast and many mammalian cells, proteasomes strongly concentrate in the nucleus. Sts1 from the yeast Saccharomyces cerevisiae is an essential protein linked to proteasome nuclear localization. Here, we show that Sts1 contains a non-canonical bipartite nuclear localization signal (NLS) important for both nuclear localization of Sts1 itself and the proteasome. ... [more]
