DBP5/YOR046C Summary Help

Standard Name DBP5 1
Systematic Name YOR046C
Alias RAT8 2
Feature Type ORF, Verified
Description Cytoplasmic ATP-dependent RNA helicase of the DEAD-box family; involved in mRNA export from the nucleus, remodeling messenger ribonucleoprotein particles (mRNPs), with ATPase activity stimulated by Gle1p, IP6 and Nup159p; involved in translation termination along with Sup45p (eRF1); role in the cellular response to heat stress (3, 4, 5, 6, 7)
