Technical Data
PI3 Kinase Class III
Three distinct types of phosphoinositide 3-kinases (PI3K) have been characterized. Unlike other PI3Ks, PI3K class III catalyzes the phosphorylation of phosphatidylinositol at the D3 position, producing phosphatidylinositol-3-phosphate (PI(3)P) (1). PI3K class III is the mammalian homolog of Vps34, first identified in yeast. PI3K class III interacts with the regular subunit p150, the mammalian homolog of Vps15, which regulates cellular membrane association through myristoylation (2,3). PI(3)P recruits several proteins with FYVE or PX domains to membranes regulating vesicular transport and protein sorting (4). Moreover, PI3K class III has been shown to regulate autophagy, trimeric G-protein signaling, and the mTOR nutrient-sensing pathway (5). Specificity/Sensitivity: PI3 Kinase Class III Antibody detects endogenous levels of total PI3K class III protein. This antibody may cross-react with an unidentified protein at ~55kD.

Suitable for use in Western Blot and Immunoprecipitation. Other applications not tested.

Recommended Dilution:
Western Blot: 1:1000
mmunoprecipitation: 1:50
Optimal dilutions to be determined by the researcher.

Storage and Stability:
For long-term storage, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
