Calcium-dependent lectin that mediates cell adhesion by binding to glycoproteins on neighboring cells (PubMed:12403782, PubMed:28011641, PubMed:28489325). Mediates the adherence of lymphocytes to endothelial cells of high endothelial venules in peripheral lymph nodes. Promotes initial tethering and rolling of leukocytes in endothelia (PubMed:12403782, PubMed:28011641). {ECO:0000269|PubMed:12403782, ECO:0000269|PubMed:28011641, ECO:0000305|PubMed:28489325}. This is the function of SELL (selectin L, Ensembl gene identifier ENSG00000188404).
