Activity summary

Phospholipase C beta 3 often called PLCB3 plays an important role in cellular signal transduction. This enzyme exists as part of the phospholipase C family enhances the conversion of phosphatidylinositol 45-bisphosphate (PIP2) into diacylglycerol (DAG) and inositol triphosphate (IP3). These molecules act as secondary messengers and are important to cellular responses. PLCB3 has a molecular mass of approximately 152 kDa. It exhibits significant expression in various tissues including the brain and heart among others where it regulates numerous physiological processes.

Biological function summary

The activation of PLCB3 influences intracellular calcium levels by producing IP3 contributing to calcium signaling pathways. As part of its biological role PLCB3 contributes to a dynamic signaling complex interacting with receptors like G-protein-coupled receptors (GPCRs) and affecting downstream signaling. This enzyme actively participates in regulating cellular processes such as proliferation and differentiation by mediating signal transduction pathways.

Pathways

PLCB3 integrates into the calcium signaling and phosphatidylinositol signaling pathways where it functions through interaction with G alpha q proteins. The activation of PLCB3 leads to the release of calcium ions from the endoplasmic reticulum a process important for many cellular functions. In these pathways PLCB3 shares interactions with other related proteins like protein kinase C (PKC) which further modulates cellular responses.

Associated diseases and disorders

Dysregulation of PLCB3 activity has links to several pathophysiological conditions including cardiovascular diseases and cancer. Abnormal PLCB3 signaling correlates with irregular calcium homeostasis impacting cardiac functions and promoting oncogenic transformations. Interactions between PLCB3 and proteins such as GPCRs highlight their importance in developing therapeutic targets for treating these diseases.
