Table S1 - Maternal Transmission of a Humanised Igf2r Allele Results in an Igf2 Dependent Hypomorphic and Non-Viable Growth Phenotype

Mass spectrometry identification of the full size IGF2R species present in both Igf2r+m/+p and Igf2rHUm/HUp mice. Sequence of the peptides matching mouse IGF2R (Q07113) or humanised IGF2R (hybrid sequence consisting of residues exon 1 to 2 from Q07113 followed by exons 3–48 from P11717). Peptides shown have rank = 1 and score>25. (DOCX)
