Conopressin S

Conopressin S, a peptide isolated from the cone snail Conus striatus, is a selective high-affinity ligand for the vasopressin V1b receptor (AVPR1B), with a Ki of 8.3 nM. It serves as a valuable research tool for investigating the receptor's role in stress, social behavior, and endocrine function in both in vitro and in vivo studies.
