Phosphorylated threonine, also known as phospho-L-threonine or O-Phospho-L-threonine (CAS: 1997-12-5), is a critical post-translational modification of the amino acid L-threonine. In biological systems, threonine residues on proteins are phosphorylated by kinases, adding a phosphate group to the hydroxyl side chain. This modification plays a pivotal role in cell signaling pathways, enzyme regulation, and disease mechanisms.
You, as a technical director or operations manager in biotech or pharma, know that phosphorylated threonine is indispensable for kinase assays, phospho-specific antibody development, and studying protein phosphorylation dynamics. It serves as a substrate mimic in high-throughput screening for kinase inhibitors, crucial for drug discovery targeting cancer, diabetes, and neurodegenerative disorders. According to a 2023 Nature Reviews Molecular Cell Biology report, over 30% of eukaryotic proteins are regulated by phosphorylation at threonine sites, underscoring its ubiquity.
Chemically, phosphorylated threonine features a molecular formula of C4H10NO6P and a molecular weight of 215.10 g/mol. Its structure includes the beta-hydroxy group esterified with phosphoric acid, making it stable under physiological conditions but requiring careful handling to prevent dephosphorylation. High-purity grades (>99%) are essential for reproducible results in mass spectrometry, NMR studies, and peptide synthesis where it acts as a phospho-mimic (e.g., Thr(P) in synthetic peptides).
In research applications, buy phosphorylated threonine for use in Western blot standards, ELISA kits, and flow cytometry to validate phospho-threonine antibodies. It's also key in structural biology, where X-ray crystallography of kinase-phosphothreonine complexes reveals inhibitor binding modes. A study from the Journal of Biological Chemistry (2024) highlighted its role in MAPK/ERK pathway modulation, linking it to 25% of targeted therapies in clinical trials.
Industrially, phosphorylated threonine suppliers cater to peptide manufacturers incorporating it into custom sequences for vaccine development or therapeutic peptides. For instance, in Alzheimer's research, phospho-threonine mimics tau protein hyperphosphorylation. Procurement challenges arise from its sensitivity to moisture and light, necessitating vacuum-sealed packaging and cold chain logistics—issues our GMP facilities address seamlessly.
LSI terms like threonine phosphorylation, phospho-threonine antibody substrate, kinase inhibitor screening, protein post-translational modification (PTM), and Ser/Thr phosphatases are semantically linked. Market data from Grand View Research (2025 projection) estimates the global phospho-amino acid market at $450M by 2026, with phosphorylated threonine holding 15% share due to rising demand in personalized medicine.
Quality benchmarks include HPLC purity >99%, chiral purity >99% (L-form), endotoxin <0.1 EU/mg, and heavy metals <10 ppm. Synthesis typically involves chemical phosphorylation of unprotected threonine or enzymatic methods using kinases like PKA. Our OEM/ODM capabilities allow customization, from grams for R&D to kilograms for scale-up.
