Predicted computational tertiary structure of wild-type (WT) and p.Ile38Ser hBEST1 proteins. 4RDQ crystal structure was used as template. (a) Homopentameric structure of WT BEST1 full structure. Red dots represent outer membrane border and blue dots represent intracellular membrane border. Isoleucine 38 position, which is located in the transmembrane (TM) domain 1, is highlighted in red. The yellow box region was magnified in (b) and (c). (b) The side chain of Ile38 in the TM1 domain was described, which consisted of a hydrophobic carbon chain (gray). The side chain protrudes toward the lipid membrane. (c) The side chain of Ser38 presents hydrophilic oxygen residue (red), which may generate a repulsive force with the hydrophobic lipid membrane.
