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.

Direct evidence that involucrin is a major early isopeptide cross-linked component of the keratinocyte cornified cell envelope.

Steinert PM, Marekov LN

Involucrin was the first protein to be identified as a likely constituent of the insoluble cornified cell envelope (CE) of stratified squamous epithelia. However, to date, direct isolation from CEs of involucrin cross-linked by way of the transglutaminase-induced isopeptide bond has not been reported. We have treated human foreskin CEs with methanol/KOH (saponification) to hydrolyze off much of the lipids. ... [more]
