STM1/YLR150W Summary Help

Standard Name STM1 1
Systematic Name YLR150W
Alias MPT4 2
Feature Type ORF, Verified
Description Protein required for optimal translation under nutrient stress; perturbs association of Yef3p with ribosomes; involved in TOR signaling; binds G4 quadruplex and purine motif triplex nucleic acid; helps maintain telomere structure; protein abundance increases in response to DNA replication stress; serves as a ribosome preservation factor both during quiescence and recovery (1, 3, 4, 5, 6, 7, 8, 9)
Name Description Suppressor of ToM1 1
