Figure 1

Comparison of mammalian and Xenopus laevis: insulin and insulin receptor structures. The upper panel compares the amino acid sequences of Porcine (Accession #P01315) and X. laevis (Accession #P12706) insulin-1. The lower panel compares the alignment of the α-subunits of the X. laevis insulin receptor (Accession #Q9PVZ4; sequence 38–754) and human insulin receptor (Accession #P06213; sequence 28–758). Data are from the unprocessed sequences as listed in the Swiss Protein Knowledgebase (http://www.uniprot.org).
