Protein phosphorylation, which plays a key role in most cellular activities, is a reversible process mediated by protein kinases and phosphoprotein phosphatases. Protein kinases catalyse the transfer of the gamma phosphate from nucleotide triphosphates (often ATP) to one or more amino acid residues in a protein substrate side chain, resulting in a conformational change affecting protein function. Phosphoprotein phosphatases catalyse the reverse process. Protein kinases fall into three broad classes, characterised with respect to substrate specificity [1]; Serine/threonine-protein kinases, tyrosine-protein kinases, and dual specificity protein kinases (e.g. MEK - phosphorylates both Thr and Tyr on target proteins). This entry represents the catalytic domain found in a number of serine/threonine- and tyrosine-protein kinases. It does not include the catalytic domain of dual specificity kinases.

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].
