The sequences of Siglec-5 protein and peptides recovered by mass spectrometric analysis of aptamer K19-enriched proteins. The Ig-like V-type domain and two Ig-like C2-type domains of Siglec-5 are underlined while the signal peptide, the transmembrane region, and the immunoreceptor tyrosine-based inhibitory (ITIM) motif are marked with dotted underlines. The peptides identified by mass spectrometry are highlighted by bordering.
