PIP4K2B antibody detects Phosphatidylinositol-5-phosphate 4-kinase type-2 beta, a lipid kinase involved in the generation of phosphatidylinositol-4,5-bisphosphate (PIP2), a key signaling molecule regulating membrane trafficking, cytoskeletal organization, and nuclear signaling. PIP4K2B phosphorylates phosphatidylinositol-5-phosphate (PI5P) at the 4-position to produce PIP2, controlling both cytoplasmic and nuclear pools of phosphoinositides. The PIP4K2B antibody is used in cell signaling and lipid metabolism research to study phosphoinositide regulation and signaling compartmentalization.
PIP4K2B is encoded by the PIP4K2B gene located on human chromosome 17q11.2. The protein is approximately 416 amino acids in length and belongs to the type II phosphatidylinositol 4-kinase family. PIP4K2B localizes to both the cytoplasm and nucleus, dynamically shuttling in response to growth factor stimulation and metabolic status. Its nuclear localization is critical for maintaining gene expression through phosphoinositide-dependent transcriptional regulation.
The PIP4K2B antibody detects a 47 kilodalton protein by western blot and reveals cytoplasmic and nuclear staining under confocal microscopy. PIP4K2B cooperates with its isoforms PIP4K2A and PIP4K2C to maintain phosphoinositide homeostasis. It modulates nuclear PIP2 levels, influencing chromatin remodeling, mRNA processing, and DNA damage responses. In the cytoplasm, PIP4K2B regulates endosomal trafficking and actin cytoskeleton reorganization, integrating lipid metabolism with cell motility.
Functionally, PIP4K2B connects metabolic signaling with growth control through crosstalk between phosphoinositide and mTOR pathways. Loss of PIP4K2B sensitizes cells to metabolic stress and DNA damage, while its overexpression enhances proliferation and survival in cancer cells. Mutations or reduced expression of PIP4K2B have been linked to metabolic disorders, insulin resistance, and neurodegeneration.
Because of its dual role in lipid signaling and nuclear regulation, PIP4K2B is a key node in phosphoinositide-mediated signal integration. NSJ Bioreagents provides a validated PIP4K2B antibody optimized for its applications, supporting research into membrane signaling, metabolism, and nuclear phosphoinositide control.
Optimal dilution of the PIP4K2B antibody should be determined by the researcher.
E.coli-derived human PIP4K2B recombinant protein (Position: D116-K360) was used as the immunogen for the PIP4K2B antibody.
After reconstitution, the PIP4K2B antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
