Biochemical Activity (Proteolytic Processing)

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.

Chromogranin A (CgA), the major soluble protein in catecholamine storage vesicles, serves as a prohormone that is cleaved into bioactive peptides that inhibit catecholamine release, providing an autocrine, negative feedback mechanism for regulating catecholamine responses during stress. However, the proteases responsible for the processing of CgA and release of bioactive peptides have not been established. Recently, we found that chromaffin ... [more]
