Rabbit Anti-HISPPD2A/IP6 Kinase antibody
This gene encodes a dual functional inositol kinase. The encoded enzyme converts inositol hexakisphosphate to diphosphoinositol pentakisphosphate and diphosphoinositol pentakisphosphate to bis-diphosphoinositol tetrakisphosphate. This protein may be important for intracellular signaling pathways. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 15.[provided by RefSeq, Jun 2010]
Function:
Bifunctional inositol kinase that catalyzes the formation of diphosphoinositol pentakisphosphate (InsP7 or PP-InsP5) and bi-diphosphoinositol tetrakisphosphate (InsP8 or PP2-InsP4). Converts inositolitol hexakisphosphate (InsP6) to InsP7. Also able to convert InsP7 to InsP8. Probably specifically mediates the formation of 4PP-InsP5 and 6PP-InsP5 InsP7 isomers but not of 5PP-IP5 InsP7 isomer. Activated when cells are exposed to hyperosmotic stress.
Subcellular Location:
Cytoplasm, cytosol.
Tissue Specificity:
Widely expressed, with a higher expression in skeletal muscle, heart and brain.
Similarity:
Belongs to the histidine acid phosphatase family. VIP1 subfamily.
