Sialylated TLR2 binds to Siglec15 as a Siglec15 receptor. a Identification of 318 potential Siglec15 binding proteins using the proximity labeling method followed by LC–MS/MS. The number of membrane proteins and glycoproteins is shown. b Most highly enriched glyco-membrane protein evaluated by the Mascot score, peak area and unique peptides. c Hierarchical clustering heatmap showing the expression of mouse TLR family members in BMMs, pOCs and mOCs detected by RNA-seq. d Immunoblotting (IB) for Siglec15 in whole-cell lysates or protein complexes immunoprecipitated (IP) with TLR2 and IB for TLR2 in whole-cell lysates or protein complexes IP with Siglec15 in the indicated groups. e IB for TLR2 in whole-cell lysates or protein complexes IP with Siglec15 in Siglec15ΔLysM or Siglec15fl/fl (WT) BMMs to test the effects of sialidase
