Neurokinin A; Substance K; Neuromedin L; NKA is a neuropeptide belonging to the tachykinin family, primarily involved in regulating inflammatory responses, immune functions, and cardiovascular processes through activation of neurokinin-2 (NK-2) receptors. It shares structural homology with Substance P and Neurokinin B but exhibits distinct receptor specificity and biological roles. This peptide plays a key role in mediating pain signaling, vasodilation, and smooth muscle contraction. In pharmacological research, it serves as a tool to investigate NK-2 receptor mechanisms, structure-activity relationships, and potential therapeutic applications for inflammatory disorders and cardiovascular diseases. Its multiple names reflect historical terminology and isoform variations.
