Definition

A large family of acidic adaptor proteins of ∼30 kDa that mainly (but not solely) interact with phosphoserine or -threonine sites on target proteins to facilitate their activity. 14-3-3 proteins have 9–10 alpha helices, generally form homo- or heterodimers, and contain a number of common modification sites (e.g. phosphorylation, divalent cation binding, and so forth) to regulate their activities, interactions, and localizations.
