Presentation Transcript

  1. Detection, localization, and function of hIP receptor mutant R212C A, Amino acid sequence of the hIP placed in a secondary structure (snake plot) format with the 7-TM helices. The N terminus is located extracellular (EC), with 2 sites of glycosylation indicated by pentagonal chains. The dual disulfide bonds are shown by the dashed line. The C terminus is intracellular (IC), with putative sites of palmitoylation–isoprenylation indicated (serrated lines). The position of the R212C is highlighted with a black arrow. B, Chromatogram from genomic DNA sequencing of cardiology patients showing the nucleotide changes at position 212 wild-type codon (CGC; I), heterozygote mutation (T/CGC; II) and homozygote mutation (TGC; III). C, Computer-derived 3D model (energyminimized) of hIP receptor showing TM helices (red) and extracellular and intracellular loops (gray). Enlarged region highlights the third intracellular loop and location of the Arg residue at position 212, at the C-terminal end of the putative transmembrane alpha-helix, the position disrupted on conversion to a cysteine (R212C) Arehart E, Stitham J, Asselbergs FW, et al.
