All the programs and data used to identify selenoproteins in the human genome. Seven novel selenoprotein genes were found by SECIS and gene prediction, together with comparative genomics approaches. We believe the human selenoproteome to consist of 17 selenoprotein families (15kDa, DI, GPX, SelH, SelI, SelK, SelM, SelN, SelO, SelP, SelR, SelS, SelT, SelV, SelW, SPS2 and TR) and, in addition, two Cys-containing homologs (MsrA and SelU), which are selenoproteins in other organisms.
