The function of Ensembl gene identifier ENSG00000105501 (SIGLEC5, sialic acid binding Ig like lectin 5) is as follows. Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Binds equally to alpha-2,3-linked and alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface.
