Reconstituted Complex

An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.

Hop2-Mnd1 functions as a DNA sequence fidelity switch in Dmc1-mediated DNA recombination.

Peng JC, Chang HY, Sun YL, Prentiss M, Li HW, Chi P

Homologous recombination during meiosis is critical for chromosome segregation and also gives rise to genetic diversity. Genetic exchange between homologous chromosomes during meiosis is mediated by the recombinase Dmc1, which is capable of recombining DNA sequences with mismatches. The Hop2-Mnd1 complex mediates Dmc1 activity. Here, we reveal a regulatory role for Hop2-Mnd1 in restricting substrate selection. Specifically, Hop2-Mnd1 upregulates Dmc1 ... [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.
