Modeling the 2xLEP–2xLEPR interaction. (A) Each of the top motifs for leptin (LEP) and leptin receptor (LEPR) are colored in respective color coding. LEP: motif 1, red; motif 2, blue. LEPR: motif 1, green; motif 2 and 4, magenta; motif 3, yellow; motif 5–7, cyan. (B) Magnified view of the Ig-like and LBD of LEPR showing the 2–2 interaction model based on vertebrate evolution. (C) Model of endogenous dimerized LEPR being activated by LEP binding.
