Research Summary

Dr. Sutkeviciute’s current research interests include investigation of the structural mechanisms of parathyroid hormone receptor (PTHR) signaling, in particular 1) the structural basis for distinct signaling modes of PTHR mediated by endogeneous hormones PTH and PTHrP as well as engineered long-acting PTH (LA-PTH); 2) determination of the structure of agonist-bound PTHR in complex with Gq heterotrimer, which will bring the fundamentally important insight to structural basis for G protein selectivity; 3) investigation of β-arrestin1 interaction with PTHR to unveil the binding epitopes and give basis for the structural model of PTHR/β-arrestin1 interaction. Another research interests involves the structure-based design of small molecule drug candidates targeting PTHR to open venues for development of novel therapies for osteoporosis, hypocalcaemia and other diseases caused by defects in PTHR signaling.
