Co-localization

Interaction inferred from two proteins that co-localize in the cell by indirect immunofluorescence only when in addition, if one gene is deleted, the other protein becomes mis-localized. Also includes co-dependent association of proteins with promoter DNA in chromatin immunoprecipitation experiments.

Spatio-temporal activation of chromatin on the human CYP24 gene promoter in the presence of 1alpha,25-Dihydroxyvitamin D3.

Vaeisaenen S, Dunlop TW, Sinkkonen L, Frank C, Carlberg C

The vitamin D3 24-hydroxylase gene (CYP24) is one of the most strongly induced genes known. Despite this, its induction by the hormone 1alpha,25-dihydroxyvitamin D3 (1alpha,25OH2D3) has been characterized only partially. Therefore, we monitored the spatio-temporal, 1alpha,25OH2D3-dependent chromatin acetylation status of the human CYP24 promoter by performing chromatin immunoprecipitation (ChIP) assays with antibodies against acetylated histone 4. This was achieved by ... [more]

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.
