14-3-3 GRF | General regulatory element

GRF (General regulatory factor 2) or 14.3.3’s are 30KDa proteins involved in protein interactions with target proteins containing phosphorylated target sites. Functions of 14.3.3’s include acting as adaptors or scaffolds, stimulating protein-protein interaction, altering target protein activity, causing conformational changes of target proteins, regulating subcellular localisation and also facilitating transport (for example nuclear import/export and transport in the endomembrane system). A variety of apparently unrelated biological activities, including a role in development and signal transduction - brassinosteroid mediated signaling pathway.
