LMPD ID
LMP010801
Gene ID
824863
Species
Arabidopsis thaliana (Arabidopsis)
Gene Name
phosphatidylinositol-4-phosphate 5-kinase 4
Gene Symbol
PIP5K4
Synonyms
phosphatidyl inositol monophosphate 5 kinase 4; PIP5K4; T8M16.6
Alternate Names
phosphatidylinositol-4-phosphate 5-kinase 4
Chromosome
3
EC Number
2.7.1.68
Summary
Encodes a protein with phosphatidylinositol-4-phosphate 5-kinase activity that plays a role in pollen tip growth. The enzyme localizes to the apical plasma membrane and adjacent cytosolic region of pollen tubes. Overexpression of this gene leads to increased deposition of pectin in the cell wall at the tip of the pollen tube and causes altered pollen tube morphology.
