Allatostatin IV

Allatostatin IV is a synthetic research peptide in the allatostatin insect neuropeptide family. Allatostatins are insect neuropeptides with several structural families. Type-A allatostatins characteristically share a C-terminal Y/FXFGL-NH2 motif and act through cognate allatostatin GPCRs. Drosophila studies have identified peptide/receptor pairs and shown that different allatostatin families can signal through distinct receptors. Individual isoforms are useful for comparative receptor activation and insect neuroendocrine research.

• allatostatin receptor assays
• insect neuroendocrine studies
• GPCR ligand selectivity experiments
• isoform structure-function comparisons

Species, isoform, residue range, amidation state, stereochemistry, and other modifications can materially affect receptor affinity and biological response. The exact construct should therefore be matched to the intended assay and published reference context.
