HAP1

CYP1, L000002665, YLR256W
Zinc finger transcription factor; involved in the complex regulation of gene expression in response to levels of heme and oxygen; localizes to the mitochondrion as well as to the nucleus; the S288C sequence differs from other strain backgrounds due to a Ty1 insertion in the carboxy terminus
Saccharomyces cerevisiae (S288c)

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.

Antibody-promoted dimerization bypasses the regulation of DNA binding by the heme domain of the yeast transcriptional activator HAP1.

Zhang L, Bermingham-McDonogh O, Turcotte B, Guarente L

The yeast transcriptional activator HAP1 contains a DNA-binding domain homologous to the zinc finger of GAL4 and an adjacent regulatory domain that blocks DNA binding in the absence of the inducer heme. We show that short HAP1 fragments containing the zinc finger are unable to bind to DNA but can be rescued by antibody to the HAP1 zinc finger. These ... [more]
