Biochemical Activity (Ubiquitination)

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

Loss of HRD1-mediated protein degradation causes amyloid precursor protein accumulation and amyloid-beta generation.

Kaneko M, Koike H, Saito R, Kitamura Y, Okuma Y, Nomura Y

Endoplasmic reticulum-associated degradation (ERAD) is a system by which proteins accumulated in the endoplasmic reticulum (ER) are retrotranslocated to the cytosol and degraded by the ubiquitin-proteasome pathway. HRD1 is expressed in brain neurons and acts as an ERAD ubiquitin ligase. Amyloid precursor protein (APP) is processed into amyloid-beta peptides (Abetas) that form plaque deposits in the brains of Alzheimer's disease ... [more]

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.
