RPT2

YHS4, YTA5, proteasome regulatory particle base subunit RPT2, L000002559, YDL007W
ATPase of the 19S regulatory particle of the 26S proteasome; one of six ATPases of the regulatory particle; involved in the degradation of ubiquitinated substrates; required for normal peptide hydrolysis by the core 20S particle; N-myristoylation of Rpt2p at Gly2 is involved in regulating the proper intracellular distribution of proteasome activity by controlling the nuclear localization of the 26S proteasome

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Separation of a functional deubiquitylating module from the SAGA complex by the proteasome regulatory particle.

Lim S, Kwak J, Kim M, Lee D

Gene expression is an intricate process tightly linked from gene activation to the nuclear export of mRNA. Recent studies have indicated that the proteasome is essential for gene expression regulation. The proteasome regulatory particle binds to the SAGA complex and affects transcription in an ATP-dependent manner. Here we report that a specific interaction between the proteasomal ATPase, Rpt2p and Sgf73p ... [more]
