Description
Product Description
Protein Kinase C β Peptide (CAS 309247-50-5) is a research-grade peptide derived from the β isoform of Protein Kinase C (PKCβ), a member of the serine/threonine kinase family that plays a crucial role in cellular signal transduction. PKCβ is activated by diacylglycerol and calcium ions and is intimately involved in modulating vascular tone, inflammation, and endothelial function.
This peptide fragment represents a functional domain of PKCβ that can be used in studies investigating kinase regulation, phosphorylation events, and downstream signaling mechanisms. Hyperglycemia has been shown to activate PKCβ, leading to endothelial dysfunction through the reduction of nitric oxide bioavailability. The use of PKCβ inhibitors—or its peptide analogs—has demonstrated the ability to restore normal endothelial-dependent vasodilation in experimental models.
Protein Kinase C β Peptide serves as a powerful research tool for exploring the molecular basis of vascular complications in diabetes, including retinopathy, nephropathy, and atherosclerosis. Researchers employ this peptide to dissect the complex interactions between PKCβ signaling and nitric oxide synthase pathways.
Beyond vascular studies, PKCβ is also implicated in immune responses, cell proliferation, and apoptosis. The peptide fragment can be used to map phosphorylation targets or design selective inhibitors for therapeutic exploration.
Applications include:
Studying PKCβ-mediated endothelial signaling
Modeling hyperglycemia-induced vascular dysfunction
Screening for kinase inhibitors in metabolic disease research
Investigating nitric oxide production and oxidative stress regulation
Protein Kinase C β Peptide is synthesized to high purity and suitable for use in in vitro biochemical assays, protein interaction studies, and cell-based experiments. It enables precise modulation of kinase activity and supports the identification of new therapeutic targets for cardiovascular and metabolic disorders.

Mechanism of Action
Protein Kinase C β (PKCβ) is activated under conditions of elevated glucose concentration, which results in increased diacylglycerol (DAG) levels and subsequent activation of PKCβ signaling pathways. Activated PKCβ phosphorylates multiple target proteins in endothelial cells, leading to decreased nitric oxide (NO) bioavailability and impaired vasodilation.
Protein Kinase C β Peptide acts as a molecular tool to study this pathway by mimicking or interfering with endogenous PKCβ interactions. Through modulation of phosphorylation cascades, the peptide enables controlled exploration of the relationship between PKCβ activity and endothelial nitric oxide synthase (eNOS) regulation.
Experimental inhibition of PKCβ or competition via this peptide fragment restores endothelium-dependent vasodilation, highlighting PKCβ’s critical role in vascular homeostasis and hyperglycemia-induced endothelial dysfunction.
