Summary
Breakdown products of phosphoinositides are ubiquitous second messengers that function downstream of many G protein-coupled receptors and tyrosine kinases regulating cell growth, calcium metabolism, and protein kinase C activity. This gene encodes an enzyme which regulates the amount of phosphatidylinositol available for signaling by catalyzing the conversion of phosphatidic acid to CDP-diacylglycerol. This enzyme is an integral membrane protein localized to two subcellular domains, the matrix side of the inner mitochondrial membrane where it is thought to be involved in the synthesis of phosphatidylglycerol and cardiolipin and the cytoplasmic side of the endoplasmic reticulum where it functions in phosphatidylinositol biosynthesis. Two genes encoding this enzyme have been identified in humans, one mapping to human chromosome 4q21 and a second to 20p13. [provided by RefSeq, Jul 2008]

Comments

Comment Type Description
Alternative Products Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=O95674-1; Sequence=Displayed; Name=2; IsoId=O95674-2; Sequence=VSP_015477, VSP_015480, VSP_015482; Note=No experimental confirmation available.;
Catalytic Activity CTP + phosphatidate = diphosphate + CDP- diacylglycerol.
Developmental Stage No expression detected at E10.5 in the developing brain. At E12.5 expression is detected in the developing sentral nervous system and peripheral nervous system. At E17.5 high levels of expression are detected in a number of sites, including the dorsal root ganglia of the peripheral nervous system and the ganglion cell layer of the neural retina in the developing eye. At this stage expression in the brain is restricted to the ventricular zone of the telencephalon, in particular in the basal ganglia and the cerebral cortex.
Function Provides CDP-diacylglycerol, an important precursor for the synthesis of phosphatidylinositol, phosphatidylglycerol, and cardiolipin.
Pathway Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 3/3.
Similarity Belongs to the CDS family.
Subcellular Location Mitochondrion inner membrane ; Multi-pass membrane protein ; Matrix side .
Tissue Specificity Widely expressed. Expressed in heart, brain and retina, and to a lesser extent in placenta, lung, liver, skeletal muscle, kidney and pancreas.
