1.MECHANISM OF ACTION

Calcium-Dependent Activation: Binds to calmodulin (CaM) upon intracellular calcium influx, forming a Ca²⁺/CaM-kinase complex that undergoes autophosphorylation and activation.

Substrate Phosphorylation: Phosphorylates serine/threonine residues on target proteins (e.g., synapsin I, myosin light chains, transcription factors), modulating their activity and cellular localization.

Signal Amplification: Acts as a molecular switch to amplify calcium signals, coordinating diverse physiological responses across tissues.

2.PRODUCT INDICATIONS

Neuroscience Research: Studies on synaptic plasticity, neurotransmitter release, and neuronal signaling pathways.

Cardiac Physiology: Investigates calcium handling, contractility, and arrhythmias in cardiomyocytes.

Cell Biology: Elucidates calcium-dependent gene expression, cell proliferation, and apoptosis mechanisms.

Drug Discovery: Screens for kinase inhibitors or activators targeting calcium signaling disorders

3.CLINICAL EFFICACY OF PRODUCT

Preclinical Validation: Demonstrates dose-dependent kinase activity in vitro, with EC₅₀ values validated in CaM-dependent phosphorylation assays using recombinant substrates.

Functional Relevance: Mimics native kinase fragment activity in cellular models, regulating synaptic vesicle trafficking and cardiac myocyte contraction in rodent studies.

Translational Potential: Serves as a benchmark compound for developing therapeutics targeting calcium-calmodulin kinase dysfunction in cardiovascular and neurological diseases.
