(a) Amino acid sequence of Themis2, indicating splice junctions (black triangles) and the location of twelve high-scoring peptides identified by LC-MS/MS (highlighted in red). (b) The sequence, mass and location of the twelve peptides analyzed in wild-type (WT1) and Themis2 exon 4 knockout mice (KO1 and 2) mice, showing the sequencing result and scored intensity of MS/MS detection for each peptide.
