Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

The Smk1p MAP kinase negatively regulates Gsc2p, a 1,3-beta-glucan synthase, during spore wall morphogenesis in Saccharomyces cerevisiae.

Huang LS, Doherty HK, Herskowitz I

Spore formation in Saccharomyces cerevisiae involves the sequential deposition of multiple spore wall layers between the prospore membranes that surround each meiotic product. The Smk1p mitogen-activated protein (MAP) kinase plays a critical role in spore formation, but the proteins that interact with Smk1p to regulate spore morphogenesis have not been described. Using mass spectrometry, we identify Gsc2p as a Smk1p-associated ... [more]

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.
