Biological Activity

Description

The L-selectin/CD62L protein is a calcium-dependent lectin that promotes cell adhesion by binding to glycoproteins on neighboring cells. L-selectin/CD62L Protein, Human (CHO, His) is the recombinant human-derived L-selectin/CD62L protein, expressed by CHO , with C-His labeled tag.

Background

L-Selectin, also known as CD62L, is a calcium-dependent lectin that plays a crucial role in mediating cell adhesion by binding to glycoproteins on neighboring cells. Functionally, it facilitates the adherence of lymphocytes to endothelial cells within high endothelial venules in peripheral lymph nodes, promoting the initial tethering and rolling of leukocytes in endothelial tissues. L-Selectin's interaction with SELPLG/PSGL1 and PODXL2 is vital for the recruitment and rolling of leukocytes. This interaction is specifically dependent on the sialyl Lewis X glycan modification of SELPLG and PODXL2, along with tyrosine sulfation modifications of SELPLG. Notably, sulfation on 'Tyr-51' of SELPLG emerges as a critical factor for effective L-Selectin binding. The multifaceted functions of L-Selectin underscore its significance in orchestrating cell adhesion processes and immune cell recruitment.
