Global proteome of PTH1R transfected U2OS cells

ABSTRACT: Brachydactyly type E (BDE), shortened metacarpals, metatarsals, cone-shaped epiphyses, and short stature, is an autosomal-dominant condition that commonly occurs as a sole phenotype. Parathyroid hormone-like protein (PTHrP) has been shown to be responsible in all forms to date, either directly or indirectly. We used linkage and then whole genome sequencing in a small pedigree, to elucidate BDE and identified a truncateddisintegrin-and-metalloproteinase-19 (ADAM19) allele in all affected family members, but not in nonaffected persons. Since we had shown earlier that the extracellular domain of the parathyroid hormone receptor (PTHR1) is subject to an unidentified metalloproteinase cleavage, we tested the hypothesis that ADAM19 is a sheddase for PTHR1. We transfected U2OS cells with ADAM19 (Control), PTH1R (disease-model), both PTH1R plus ADAM19 (healthy), and no transfection at all as another control. We did global proteome on these cell lines and compared them using a student t test.
