YPT1

Rab family GTPase YPT1, YP2, L000002543, YFL038C
Rab family GTPase; involved in the ER-to-Golgi step of the secretory pathway; complex formation with the Rab escort protein Mrs6p is required for prenylation of Ypt1p by protein geranylgeranyltransferase type II (Bet2p-Bet4p); binds to unspliced HAC1 mRNA; regulates unfolded protein response (UPR) by promoting the decay of HAC1 RNA
Saccharomyces cerevisiae (S288c)

Phenotypic Suppression

A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Ypt1 suppresses defects of vesicle trafficking and autophagy in Ypt6 related mutants.

Ye M, Chen Y, Zou S, Yu S, Liang Y

Ypt/Rab GTPases coordinately regulate vesicle trafficking in yeasts. Previously, Ypt1 was shown to suppress growth defects of Ypt6 and its related mutants (ypt6ts, ric1∆, rgp1∆, ric1∆rgp1∆), but the physiological role of this suppression has not been well studied. We have investigated the effects of Ypt1 on two major trafficking pathways, vesicle trafficking and autophagy, in Ypt6 related mutants. Ypt1 restores ... [more]

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.

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
