Updated project metadata. Background : The G protein-coupled receptor (GPCR) calcitonin receptor-like receptor (CLR) is implicated in cardiovascular and skin diseases, migraine and cancer. Beyond its agonists, receptor activity-modifying proteins and receptor component protein, interacting partners of this GPCR (‘CLR interactome’) are currently unknown. Herein, we defined CLR interactome in primary human dermal lymphatic endothelial cells (HDLEC). Immunoprecipitation (IP) of core- and terminally-glycosylated CLR and label-free quantitative mass spectrometry allowed the identification of 46 novel interaction partners from a total HDLEC proteome consisting of 4,902 proteins. Aims: The main aim of this study was to characterise the interactome of endogenous CLR along with the expression of this GPCR in the context of the proteomic profile of primary human dermal lymphatic endothelial cells cultured in vitro. Methods We used label-free quantitative proteomic analysis to analyse the CLR co-IP eluates and total protein lysates obtained from cultured in vitro primary human dermal lymphatic endothelial cells (from Promocell).
