英语百科

FMRFamide

FMRFamide (Phe-Met-Arg-Phe) is a neuropeptide from a broad family of FMRFamide-related peptides (FaRPs) all sharing an -RFamide sequence at their C-terminus. First identified in Hard clam Mercenaria mercenaria it is thought to play an important role in cardiac activity regulation. Several FMRFamid related peptides are known, regulating various cellular functions and possessing pharmacological actions, such as anti-opiate effects. In Mercenaria mercenaria, FMRFamide has been isolated and demonstrated to increase both the force and frequency of the heartbeat through a biochemical pathway that is thought to involve the increase of cytoplasmic cAMP in the ventricular region (Higgins et al., 1978).
