The siglecs (sialic acid-binding Ig-like lectins) are a distinct subset of the Ig superfamily with adhesion-molecule-like structure.
We describe here a novel member of the siglec protein family that shares a similar structure including five Ig-like domains, a transmembrane domain, and a cytoplasmic tail containing two ITIM-signaling motifs.
Siglec-10 was identified through database mining of an asthmatic eosinophil EST library.
The Siglec-10-VAP-1 interaction seems to mediate lymphocyte adhesion to endothelium and has the potential to modify the inflammatory microenvironment via the enzymatic end products.
特徴
This protein carries a human IgG1 Fc (L118A, G120A, E201A) tag at the C-terminus.
The protein has a calculated MW of 84.6 kDa.
As the result of the mutations for Fc-Tag, the protein migrates as 90-110 kDa (Siglect-10 with Fc-Tag), 60-67 kDa (Siglect-10) and 30-32 kDa (Fc fragment) under reducing (R) condition (SDS-PAGE) due to glycosylation.
Mutations (L118A, G120A, E201A /EU number: L235A/G237A/E318A) in human immunoglobulin G1 (hIgG1) Fc strongly reduce binding of the Fc mutant to cell expressed FcγRs, resulting in an almost 4-fold reduction in ADCC compared to that of wild type human IgG1.
