'Molecular sandwiches' as a basis for structural and functional similarities for interferons, MSH, ACTH, LHRH, myelin basic protein, and albumins.
Sequential similarities between the tryptophan peptide of myelin basic protein (residues 111-121), luteinizing hormone releasing hormone, melanotropin, adrenocorticotropin (residues 1-13), human leukocyte interferon (residues 28-40), and various segments of human and bovine serum albumin and hen ovalbumin are presented. It is suggested that these structural similarities may explain observations concerning common functional characteristics such as serotonin modulation, immunological activity with the adjuvant muramyl dipeptide, immunological cross-reactivity, and the possible MSH-ACTH-like activity of a pepsin-derived peptide of interferon.
