Functions

Description
EC Number 2.7.1.67 Phosphotransferases with an alcohol group as acceptor
Subcellular Localization
  • Endomembrane system
  • Mitochondrion outer membrane ; Peripheral membrane protein
  • Rough endoplasmic reticulum membrane ; Peripheral membrane protein
  • Golgi apparatus
  • Golgi apparatus membrane
  • Found in the outer membrane of mitochondria and membranes of the rough endoplasmic reticulum
  • Recruited to the Golgi complex by the small GTPase ARF to stimulate the synthesis of phosphatidylinositol 4,5-bisphosphate (PIP2) on the Golgi complex
  • Recruited to the Golgi apparatus membrane by ACBD3, GGA2 is also involved in the recruitment

3 GO annotations of molecular function

Name Definition
1-phosphatidylinositol 4-kinase activity Catalysis of the reaction: 1-phosphatidyl-1D-myo-inositol + ATP = 1-phosphatidyl-1D-myo-inositol 4-phosphate + ADP + 2 H(+).
14-3-3 protein binding Binding to a 14-3-3 protein. A 14-3-3 protein is any of a large family of approximately 30kDa acidic proteins which exist primarily as homo- and heterodimers within all eukaryotic cells, and have been implicated in the modulation of distinct biological processes by binding to specific phosphorylated sites on diverse target proteins, thereby forcing conformational changes or influencing interactions between their targets and other molecules. Each 14-3-3 protein sequence can be roughly divided into three sections: a divergent amino terminus, the conserved core region and a divergent carboxy-terminus. The conserved middle core region of the 14-3-3s encodes an amphipathic groove that forms the main functional domain, a cradle for interacting with client proteins.
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.

2 GO annotations of biological process

Name Definition
phosphatidylinositol-mediated signaling The series of molecular signals in which a cell uses a phosphatidylinositol-mediated signaling to convert a signal into a response. Phosphatidylinositols include phosphatidylinositol (PtdIns) and its phosphorylated derivatives.
phosphorylation The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
