Rabbit anti-Human PI4K2A Polyclonal Antibody

Uniprot Id

Q9BTU6

Target Species

Human

Target Name

PI4K2A

Target Full Name

Phosphatidylinositol 4-kinase type 2-alpha

Target Function

Membrane-bound phosphatidylinositol-4 kinase (PI4-kinase) that catalyzes the phosphorylation of phosphatidylinositol (PI) to phosphatidylinositol 4-phosphate (PI4P), a lipid that plays important roles in endocytosis, Golgi function, protein sorting and membrane trafficking and is required for prolonged survival of neurons. Besides, phosphorylation of phosphatidylinositol (PI) to phosphatidylinositol 4-phosphate (PI4P) is the first committed step in the generation of phosphatidylinositol 4,5-bisphosphate (PIP2), a precursor of the second messenger inositol 1,4,5-trisphosphate (InsP3).

Target Subcellular Location

Golgi apparatus, trans-Golgi network membrane; Lipid-anchor. Membrane raft. Cell projection, dendrite. Cell junction, synapse, presynaptic cell membrane. Cell junction, synapse, synaptosome. Mitochondrion. Endosome. Cytoplasmic vesicle. Membrane; Lipid-anchor. Cell membrane. Perikaryon. Cell projection, neuron projection.

Target Protein Families

PI3/PI4-kinase family, Type II PI4K subfamily

Target Tissue Specificity

Widely expressed. Highest expression is observed in kidney, brain, heart, skeletal muscle, and placenta and lowest expression is observed in colon, thymus, and small intestine.

Target Synonyms

PI4K2A; Phosphatidylinositol 4-kinase type 2-alpha; EC 2.7.1.67; Phosphatidylinositol 4-kinase type II-alpha

Target Background

Phosphatidylinositolpolyphosphates (PtdInsPs) are centrally involved in many biologic processes, ranging from cell growth and organization of the actin cytoskeleton to endo- and exocytosis. PI4KII phosphorylates PtdIns at the D-4 position, an essential step in the biosynthesis of PtdInsPs (Barylko et al., 2001 [PubMed 11244087]).
