NPY receptor subtypes (Y1-Y5) evolved through gene duplication from an ancestral receptor, with each subtype acquiring distinct tissue distribution and function — explaining NPY's diverse roles in appetite, anxiety, blood pressure, and circadian rhythm.
Key findingNPY receptor subtypes Y1-Y5 evolved through ancient gene duplications, with each acquiring distinct tissue distribution and functional specialization
What the researchers found
NPY receptor subtypes Y1-Y5 evolved through ancient gene duplications, with each acquiring distinct tissue distribution and functional specialization — Y1 for anxiety/vasoconstriction, Y2 for presynaptic inhibition, Y4 for PP binding, Y5 for feeding.
