Diacylglycerol kinase catalytic domain (presumed); Diacylglycerol (DAG) is a second messenger that acts as a protein kinase C activator. DAG can be produced from the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) by a phosphoinositide-specific phospholipase C and by the degradation of phosphatidylcholine (PC) by a phospholipase C or the concerted actions of phospholipase D and phosphatidate phosphohydrolase. This domain is presumed to be the catalytic domain. Bacterial homologues areknown.

second protein kinase C conserved region 1 (C1 domain) found in type I diacylglycerol kinases; Diacylglycerol (DAG) kinase (EC 2.7.1.107) is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid. Type I DAG kinases (DGKs) contain EF-hand structures that bind Ca(2+) and recoverin homology domains, in addition to C1 and catalytic domains that are present in all DGKs. Type I DGKs, regulated by calcium binding, include three DGK isozymes (alpha, beta and gamma). DAG kinase alpha, also called 80 kDa DAG kinase, or diglyceride kinase alpha (DGK-alpha), is active upon cell stimulation, initiating the resynthesis of phosphatidylinositols and attenuating protein kinase C activity. DAG kinase beta, also called 90 kDa DAG kinase, or diglyceride kinase beta (DGK-beta), exhibits high phosphorylation activity for long-chain diacylglycerols. DAG kinase gamma, also called diglyceride kinase gamma (DGK-gamma), reverses the normal flow of glycerolipid biosynthesis by phosphorylating diacylglycerol back to phosphatidic acid. Members of this family contain two copies of the C1 domain. This model corresponds to the second one. DGK-alpha contains atypical C1 domains, while DGK-beta and DGK-gamma contain typical C1 domains that bind DAG and phorbol esters. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

protein kinase C conserved region 1 (C1 domain) superfamily; The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains. It contains the motif HX12CX2CXnCX2CX4HX2CX7C, where C and H are cysteine and histidine, respectively; X represents other residues; and n is either 13 or 14. C1 has a globular fold with two separate Zn(2+)-binding sites. It was originally discovered as lipid-binding modules in protein kinase C (PKC) isoforms. C1 domains that bind and respond to phorbol esters (PE) and diacylglycerol (DAG) are referred to as typical, and those that do not respond to PE and DAG are deemed atypical. A C1 domain may also be referred to as PKC or non-PKC C1, based on the parent protein's activity. Most C1 domain-containing non-PKC proteins act as lipid kinases and scaffolds, except PKD which acts as a protein kinase. PKC C1 domains play roles in membrane translocation and activation of the enzyme.

second protein kinase C conserved region 1 (C1 domain) found in the diacylglycerol kinase family; The diacylglycerol kinase (DGK, EC 2.7.1.107) family of enzymes plays critical roles in lipid signaling pathways by converting diacylglycerol to phosphatidic acid, thereby downregulating signaling by the former and upregulating signaling by the latter second messenger. Ten DGK family isozymes have been identified to date, which possess different interaction motifs imparting distinct temporal and spatial control of DGK activity to each isozyme. They have been classified into five types (I-V), according to domain architecture and some common features. All DGK isozymes, except for DGKtheta, contain two copies of the C1 domain. This model corresponds to the second one. DGKtheta harbors three C1 domains. Its third C1 domain is included here.
