The peptide activates extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation in a dose-dependent manner, leading to nuclear translocation and activation of transcription factors including c-Fos, c-Jun, and early growth response-1 (Egr-1) that drive expression of genes involved in cell growth, migration, and angiogenesis
Vigorous shaking causes foaming and can lead to peptide aggregation or denaturation
