MPT5/YGL178W Summary Help

Standard Name MPT5 1
Systematic Name YGL178W
Alias HTR1 , PUF5 , UTH4
Feature Type ORF, Verified
Description mRNA-binding protein of the PUF family; binds to the 3' UTR of specific mRNAs, including those involved in mating type switching, cell wall integrity, chronological lifespan, chromatin modification, and spindle pole body architecture; recruits the CCR4-NOT deadenylase complex to mRNAs along with Dhh1p and Dcp1p to promote deadenylation, decapping, and decay; also interacts with the Caf20p translational initiation repressor, affecting its mRNA target specificity (1, 2, 3, 4, 5, 6, 7, 8, 9)
Name Description Multicopy suppressor of Pop Two 10
