POR1

OMP2, porin POR1, VDAC, YVDAC1, L000001302, YNL055C
Mitochondrial porin (voltage-dependent anion channel); outer membrane protein required for maintenance of mitochondrial osmotic stability and mitochondrial membrane permeability; couples the glutathione pools of the intermembrane space (IMS) and the cytosol; interacts with Om45 and Om14 in the outer membrane; phosphorylated; protein abundance increases in response to DNA replication stress
Saccharomyces cerevisiae (S288c)

TIM22

L000004157, YDL217C
Essential core component of the mitochondrial TIM22 complex; involved in insertion of polytopic proteins into the inner membrane; forms the channel through which proteins are imported

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.

Dual Role of Mitochondrial Porin in Metabolite Transport across the Outer Membrane and Protein Transfer to the Inner Membrane.

Ellenrieder L, Dieterle MP, Doan KN, Martensson CU, Floerchinger A, Campo ML, Pfanner N, Becker T

The mitochondrial inner membrane harbors a large number of metabolite carriers. The precursors of carrier proteins are synthesized in the cytosol and imported into mitochondria by the translocase of the outer membrane (TOM) and the carrier translocase of the inner membrane (TIM22). Molecular chaperones in the cytosol and intermembrane space bind to the hydrophobic precursors to prevent their aggregation. We ... [more]

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.
