Background Siglec-5 shares an almost identical sequence with Siglec-14 within the first two Ig-like domains, indicating partial gene conversion between these two Siglecs, also evident in other primate species.
Siglec-5, also known as CD170, is a sialic-acid-binding Ig-like lectin, and member of the Ig superfamily, expressed by dendritic cells (DCs), activated macrophages, neutrophils, and cells of the monocyte/myeloid lineage. Highly related to the myelomonocytic-derived adhesion molecule CD33 (Siglec-3), Siglec-5 mediates sialic-acid dependent binding to cells, and is as well acting as an inhibitory receptor in the down-regulation of cell activation. Structurally, Siglec-5 contains an immunoreceptor tyrosine-based inhibitor motif (ITIM), which plays a part in the modulation of cellular responses, and when phosphorylated, can bind to the SH2 domain of several SH2-containing phosphatases.
Siglec-14 is a putative sialic-acid binding adhesion molecule and predominantly expressed in hematopoietic tissues, which have been shown to associate with the activating adapter protein DAP12.
