⚛️ The World of Inositols
Inositols and D-myo-Inositols
Inositols, particularly D-myo-inositol, are fundamental sugar alcohols involved in diverse cellular processes. They act as precursors to phospholipids and regulate membrane dynamics, signal transduction, insulin sensitivity, and calcium homeostasis.
Phosphoinositides and Phosphatidylinositols (PtdIns)
These membrane lipids serve as docking sites for signaling proteins and are involved in:
- Endocytosis and exocytosis
- Membrane identity and trafficking
- Cell polarization and growth control
Inositol Phosphate Signaling Molecules such as InsP3
InsP3 is a central molecule in intracellular calcium signaling, releasing calcium from stores to trigger processes like muscle contraction and gene expression.
🧪 Key Enzymes & Pathways
PI 3-Kinases (PI3Ks)
Phosphoinositide 3-kinases (PI3Ks) catalyze the addition of a phosphate group to phosphatidylinositol-4,5-bisphosphate (PtdIns(4,5)P₂), producing phosphatidylinositol-3,4,5-trisphosphate (PIP₃).
PIP₃ acts as a second messenger that recruits and activates various downstream effectors, most notably AKT (protein kinase B), a central regulator of cell growth, survival, metabolism, and angiogenesis. Dysregulation of PI3K signaling is a hallmark of many human cancers, making PI3Ks a critical therapeutic target.
PtdIns 4-Kinases (PtdIns4Ks) and PIP/PIP5Ks
These kinases are responsible for generating key phosphoinositide precursors:
- PtdIns4Ks phosphorylate phosphatidylinositol (PtdIns) to form PtdIns4P.
- PIP5Ks (phosphatidylinositol-4-phosphate 5-kinases) further phosphorylate PtdIns4P to produce PtdIns(4,5)P₂, a central hub in phosphoinositide metabolism.
PTEN (Phosphatase and Tensin Homolog)
PTEN is a tumor suppressor phosphatase that antagonizes PI3K activity by converting PIP₃ back to PIP₂. This action serves as a brake on cell proliferation and survival signals.
Loss or mutation of PTEN is frequently observed in cancers, resulting in unchecked activation of the PI3K/AKT/mTOR axis and contributing to tumor progression, metastasis, and resistance to therapy.

Antiserum to PTEN,
From Rabbit. Immunogen: Raised against a fusion protein containing the C-terminal human PTEN sequence. Specificity: Detects a ~60 kDa band of human, mouse and rat PTEN by Western Blot
Research Applications: Immunoblotting:1:1000 Dilution, Immunoprecipitation: 1-2 ul/sample, Lipid Phosphatase Assay: Details available, IP-Phosphatase Assay: Details available.
PTEN plays an important role in the modulation of the 1-phosphatidylinositol 3-kinase pathway, by catalyzing the degradation of the PtdIns(3,4,5)P3 generated by PtdIns 3-kinase. This inhibits downstream functions mediated by PtdIns 3-kinase pathway.
