Rabbit anti-Human PI4K2B Polyclonal Antibody

Uniprot Id

Q8TCG2

Target Species

Human

Target Name

PI4K2B

Target Full Name

Phosphatidylinositol 4-kinase type 2-beta

Target Function

Together with PI4K2A and the type III PI4Ks (PIK4CA and PIK4CB) it contributes to the overall PI4-kinase activity of the cell. This contribution may be especially significant in plasma membrane, endosomal and Golgi compartments. The phosphorylation of phosphatidylinositol (PI) to 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). Contributes to the production of InsP3 in stimulated cells and is likely to be involved in the regulation of vesicular trafficking.

Target Subcellular Location

Cytoplasm. Membrane. Note=Mostly cytoplasmic but also found associated with the plasma membrane, the Golgi and endosomes. Compared to PI4K2A, a larger fraction of PI4K2B is cytosolic due to a smaller extent of palmitoylation. Translocates to membranes where it is recruited by PDGF stimulation by a Rac-GTP-dependent mechanism.

Target Protein Families

PI3/PI4-kinase family, Type II PI4K subfamily

Target Tissue Specificity

Widely expressed.

Target Background

This gene encodes a member of the type II PI4 kinase protein family. The encoded protein is primarily cytosolic and contributes to overall PI4-kinase activity along with other protein family members. This protein is involved in early T cell activation.
