title: [Synthetic peptide immunorphin as an instrument for studying nonopioid beta-endorphin receptor].
abstract: Research results of the synthetic decapeptide SLTCLVKGFY (the author's term is immunorphin) corresponding to the 364-373 sequence of G heavy-chain human immunoglobulin are summarized. Special attention is paid to the interaction between immunorphin and a nonopioid (insensitive to the opioid antagonist naloxone) beta-endorphin receptor. Using radioligand analysis, data were found regarding the distribution and functions of a nonopioid beta-endorphin receptor in human and animal bodies and the binding characteristics of immunorphin with a nonopioid receptor.
