简介内容:Gap19 TFA is a selective and potent blocker of connexin 43 (Cx43) hemichannels, originating from nine amino acids within the Cx43 cytoplasmic loop (CL). It operates by hindering intramolecular interactions between the C-terminus (CT) and the CL, effectively inhibiting hemichannel activity without affecting GJ channels or Cx40/pannexin-1 hemichannels. This peptide offers protective benefits for the myocardium.
