MSO1

L000003070, YNR049C
Probable component of the secretory vesicle docking complex; acts at a late step in secretion; shows genetic and physical interactions with Sec1p; required for prospore membrane formation during sporulation; relocalizes from bud neck to nucleus upon DNA replication stress
Saccharomyces cerevisiae (S288c)
PREY

SEC8

L000001834, YPR055W
Essential 121 kDa subunit of the exocyst complex; the exocyst mediates polarized targeting and tethering of post-Golgi secretory vesicles to active sites of exocytosis at the plasma membrane prior to SNARE-mediated fusion; involved in ER and Golgi inheritance in small buds; relocalizes away from bud neck upon DNA replication stress
Saccharomyces cerevisiae (S288c)

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.

Mso1p: a yeast protein that functions in secretion and interacts physically and genetically with Sec1p.

Aalto MK, Jaentti J, Ostling J, Keraenen S, Ronne H

The yeast Sec1p protein functions in the docking of secretory transport vesicles to the plasma membrane. We previously have cloned two yeast genes encoding syntaxins, SSO1 and SSO2, as suppressors of the temperature-sensitive sec1-1 mutation. We now describe a third suppressor of sec1-1, which we call MSO1. Unlike SSO1 and SSO2, MSO1 is specific for sec1 and does not suppress ... [more]

A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.
