ATG18

AUT10, CVT18, NMR1, SVP1, phosphoinositide binding protein ATG18, YFR021W
Phosphoinositide binding protein; required for vesicle formation in autophagy and the cytoplasm-to-vacuole targeting (Cvt) pathway; binds both phosphatidylinositol (3,5)-bisphosphate and phosphatidylinositol 3-phosphate; WD-40 repeat protein; relocalizes from vacuole to cytoplasm upon DNA replication stress; has 4 mammalian homologs WIPI1, WIPI2, WIPI3 and WIPI4/WDR45; mutations in human WDR45 cause static encephalopathy of childhood with neurodegeneration in adulthood
Saccharomyces cerevisiae (S288c)
PREY

ATG21

HSV1, MAI1, YPL100W
Phosphoinositide binding protein; required for vesicle formation in the cytoplasm-to-vacuole targeting (Cvt) pathway; binds both phosphatidylinositol (3,5)-bisphosphate and phosphatidylinositol 3-phosphate; WD-40 repeat protein
Saccharomyces cerevisiae (S288c)

Phenotypic Enhancement

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

Roles of the lipid-binding motifs of Atg18 and Atg21 in the cytoplasm to vacuole targeting pathway and autophagy.

Nair U, Cao Y, Xie Z, Klionsky DJ

Atg18 and Atg21 are homologous WD-40 repeat proteins that bind phosphoinositides via a novel conserved Phe-Arg-Arg-Gly motif and function in autophagy-related pathways. Atg18 is required for the cytoplasm to vacuole targeting (Cvt) pathway and autophagy, whereas Atg21 is only required for the Cvt pathway. Currently, the functions of both proteins are poorly understood. Here, we examined the relationship between the ... [more]

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.
