The protein encoded by this gene catalyzes the formation of inositol 1,4,5-trisphosphate and diacylglycerol from phosphatidylinositol 4,5-bisphosphate. This reaction uses calcium as a cofactor and plays an important role in the intracellular transduction of many extracellular signals. This gene is activated by two G-protein alpha subunits, alpha-q and alpha-11. Two transcript v... See more...

Entrez Gene Summary for PLCB1 Gene

  • The protein encoded by this gene catalyzes the formation of inositol 1,4,5-trisphosphate and diacylglycerol from phosphatidylinositol 4,5-bisphosphate. This reaction uses calcium as a cofactor and plays an important role in the intracellular transduction of many extracellular signals. This gene is activated by two G-protein alpha subunits, alpha-q and alpha-11. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for PLCB1 Gene

PLCB1 (Phospholipase C Beta 1) is a Protein Coding gene. Diseases associated with PLCB1 include Developmental And Epileptic Encephalopathy 12 and Malignant Migrating Partial Seizures Of Infancy. Among its related pathways are Apelin signaling pathway and G-Beta Gamma Signaling. Gene Ontology (GO) annotations related to this gene include calcium ion binding and enzyme binding. An important paralog of this gene is PLCB3.

UniProtKB/Swiss-Prot Summary for PLCB1 Gene

  • Catalyzes the hydrolysis of 1-phosphatidylinositol 4,5-bisphosphate into diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) and mediates intracellular signaling downstream of G protein-coupled receptors (PubMed:9188725). Regulates the function of the endothelial barrier.

Tocris Summary for PLCB1 Gene

  • Phospholipases are a group of enzymes that hydrolyze phospholipids into fatty acids and other lipophilic molecules. There are four major classes; phospholipase A, phospholipase B, phosphoinositide-specific phospholipase C and phospholipase D.

  • Epileptic encephalopathy, early infantile, 12 (EIEE12) [MIM:613722]: A form of epilepsy characterized by frequent tonic seizures or spasms beginning in infancy with a specific EEG finding of suppression-burst patterns, characterized by high-voltage bursts alternating with almost flat suppression phases. Patients may progress to West syndrome, which is characterized by tonic spasms with clustering, arrest of psychomotor development, and hypsarrhythmia on EEG. {ECO:0000269 PubMed:20833646}. Note=The disease is caused by variants affecting the gene represented in this entry.
