epsilon v1 2

Epsilon-V1-2 has been extensively investigated for its function as a PKC epsilon (PKCε) inhibitor. Epsilon-V1-2 has been widely applied in studies addressing ovarian aging, apoptosis in human granulosa cells, cerebral ischemia-reperfusion injury, brain development, hepatocyte insulin signaling, and neuronal cell death under ischemic conditions. Epsilon-V1-2 has been shown to effectively reduce PKCε activity, thereby enabling detailed exploration of regulatory pathways involving mitochondrial dynamics, calcium overload, AKT activation, brain atrophy, insulin resistance, and ferroptosis. Epsilon-V1-2 demonstrates notable therapeutic relevance in models of stroke, SHORT syndrome, hepatic steatosis, and brain injury, supporting its continued evaluation as a potential pharmacological agent across multiple disease contexts.

Epsilon-V1-2, a Cys-conjugated, is a biologically active peptide known as the εPKC-specific inhibitor. It hampers εPKC functionality by obstructing its translocation and the phosphorylation of MARCKS, additionally perturbing εPKC's interaction with its anchoring protein, εRACK. The peptide includes a cysteine residue at its C-terminus, facilitating the formation of potential disulfide bonds with carrier proteins. Pyroglutamyl formation can occur spontaneously at the N-terminus if glutamine or glutamic acid is present, enhancing peptide stability against gastrointestinal proteases. Pyroglutamyl peptides, a recognized subset, are accounted for in the peptide's purity during HPLC analysis.
