title: Triplet puzzle: homologies of receptor heteromers.
abstract: Based on a mathematical approach, we deduce a set of triplet homologies that may be responsible for receptor-receptor interactions. We show how such triplets of amino acid residues and their 'teams' may be utilized to construct a kind of code that determines (and/or predicts) which receptors should or should not form heterodimers. Based on the obtained results, we propose a 'guide-and-clasp' manner for receptor-receptor interactions where 'adhesive guides' might be the triplet homologies. We also demonstrate their relevance to protein-protein interactions and mention possible implications for novel pharmacological targets and strategies for treatment of diseases, e.g. neuroinflammatory diseases.
