Descriptions

PLCB1 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. Autoinhibitory region is a portion of the linker that separates the conserved X and Y boxes comprising the catalytic TIM barrel, at residues 468-539, and occludes the active site of PLCB1. The active site of a PLC isozyme toward phospholipid membranes should force the negatively charged X/Y linker away from the active site, therein relieving autoinhibition of the enzyme.

1 GO annotations of cellular component

Name Definition
trans-Golgi network The network of interconnected tubular and cisternal structures located within the Golgi apparatus on the side distal to the endoplasmic reticulum, from which secretory vesicles emerge. The trans-Golgi network is important in the later stages of protein secretion where it is thought to play a key role in the sorting and targeting of secreted proteins to the correct destination.

2 GO annotations of molecular function

Name Definition
GTP binding Binding to GTP, guanosine triphosphate.
GTPase activity Catalysis of the reaction

3 GO annotations of biological process

Name Definition
intracellular protein transport The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.
protein localization to Golgi membrane A process in which a protein is transported to, or maintained in, a location within a Golgi membrane.
vesicle-mediated transport A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.
