Product Category: Polyclonal Antibodies

Host: Rabbit

Species Reactivity: H

Cellular Localisation: Cell membrane {ECO:0000250|UniProtKB:O70172}. Nucleus. Lysosome {ECO:0000250|UniProtKB:O70172}. Cytoplasm. Photoreceptor inner segment {ECO:0000250|UniProtKB:O70172}. Cell projection, cilium, photoreceptor outer segment {ECO:0000250|UniProtKB:O70172}. Note=May translocate from the cytosol to the cell membrane upon activation of tyrosine phosphorylation. May translocate from the inner to the outer segments of the rod photoreceptor cells in response to light (By similarity) Localization to the nucleus is modulated by the interaction with PIP4K2B. {ECO:0000250|UniProtKB:O70172, ECO:0000269|PubMed:20583997}

Molecular Weight: 46225

Clone: Polyclonal

Gene Name: PIP4K2A (HGNC:8997)

Gene ID: 5305

Function: Catalyzes the phosphorylation of phosphatidylinositol 5- phosphate (PtdIns5P) on the fourth hydroxyl of the myo-inositol ring, to form phosphatidylinositol 4, 5-bisphosphate (PtdIns (4, 5) P2) (PubMed:9367159, PubMed:23326584) . Has both ATP- and GTP-dependent kinase activities (PubMed:26774281) . May exert its function by regulating the levels of PtdIns5P, which functions in the cytosol by increasing AKT activity and in the nucleus signals through ING2 (PubMed:18364242) . May regulate the pool of cytosolic PtdIns5P in response to the activation of tyrosine phosphorylation (By similarity) . Required for lysosome-peroxisome membrane contacts and intracellular cholesterol transport through modulating peroxisomal PtdIns (4, 5) P2 level (PubMed:29353240) . In collaboration with PIP4K2B, has a role in mediating autophagy in times of nutrient stress (By similarity) . Required for autophagosome-lysosome fusion and the regulation of cellular lipid metabolism (PubMed:31091439) . May be involved in thrombopoiesis, and the terminal maturation of megakaryocytes and regulation of their size (By similarity) . Negatively regulates insulin signaling through a catalytic-independent mechanism (PubMed:31091439) . PIP4Ks interact with PIP5Ks and suppress PIP5K-mediated PtdIns (4, 5) P2 synthesis and insulin-dependent conversion to PtdIns (3, 4, 5) P3 (PubMed:31091439) .

Summary: Tissue Location: Expressed ubiquitously, with high levels in the brain. Present in most tissues, except notably skeletal muscle and small intestine.

Form: Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is prepared by Saturated Ammonium Sulfate (SAS) precipitation followed by dialysis against PBS.

Storage: Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
