KSP1

putative serine/threonine protein kinase KSP1, L000000921, YHR082C
Serine/threonine protein kinase; associates with TORC1 and likely involved in TOR signaling cascades; negative regulator of autophagy; nuclear translocation required for haploid filamentous growth; regulates filamentous growth induced nuclear translocation of Bcy1p, Fus3p, and Sks1p; overproduction causes allele-specific suppression of prp20-10; protein abundance increases in response to DNA replication stress

APG1, AUT3, CVT10, serine/threonine protein kinase ATG1, L000003955, S000028502, L000004761, YGL180W
Protein serine/threonine kinase; required for vesicle formation in autophagy and the cytoplasm-to-vacuole targeting (Cvt) pathway; structurally required for phagophore assembly site formation; during autophagy forms a complex with Atg13p and Atg17p; essential for cell cycle progression from G2/M to G1 under nitrogen starvation

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.

Publication

The Ksp1 kinase regulates autophagy via the target of rapamycin complex 1 (TORC1) pathway.

Umekawa M, Klionsky DJ

Macroautophagy (hereafter autophagy) is a bulk degradation system conserved in all eukaryotes, which engulfs cytoplasmic components within double-membrane vesicles to allow their delivery to, and subsequent degradation within, the vacuole/lysosome. Autophagy activity is tightly regulated in response to the nutritional state of the cell, and also to maintain organelle homeostasis. In nutrient-rich conditions, Tor kinase complex 1 (TORC1 ) is ...

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.
