Application: Autocamtide-2 is a synthetic peptide substrate selectively phosphorylated by Ca²⁺/calmodulin-dependent protein kinases. Derived from the autophosphorylation site of CaMKII, this peptide provides a defined and reliable substrate for measuring CaMK activity in biochemical assays. Autocamtide-2 is widely used to investigate calcium-dependent signaling pathways involved in neuronal function, synaptic plasticity, muscle contraction, and cellular regulation. It supports kinase activity assays, enzyme kinetics, phosphorylation studies, inhibitor screening, and signal transduction research focused on CaMK-regulated mechanisms. Autocamtide-2 is a standard reference substrate for CaMK pathway analysis.
