SH3 (Src homology 3) domains are often indicative of a protein involved in signal transduction related to cytoskeletal organisation. First described in the Src cytoplasmic tyrosine kinase Swiss:P12931. The structure is a partly opened beta barrel.

This entry represents an EF-hand like domain found in phosphoinositol-specific phospholipase C gamma proteins. PLCG1 plays a role in actin reorganisation and cell migration [1]. PLGC1 has a critical role in maintaining immune homeostasis [2]. PLCG2 is a crucial enzyme in transmembrane signalling. This protein has been associated with several disorders [3,4]. PLCG structure comprises several key domains: an N-terminal PH domain, EF-hand motifs, catalytic X and Y domains forming a TIM-barrel, a C2 domain, a split PH domain, two SH2 domains (N-terminal and C-terminal), and an SH3 domain [5-7]. This domain is also found in the orthologue from C.elegans 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase gamma plc-3, which regulates basal and ovulatory sheath cell contractions [8].
