CD162/PSGL-1 Protein, Mouse (HEK293, His)

The CD162/PSGL-1 protein is an SLe(x)-type proteoglycan that mediates rapid rolling of leukocytes through high-affinity interactions with E- and P-selectin, thereby promoting early inflammatory stages.CD162 forms homodimers linked by disulfide bonds and interacts with selectins through the lectin/EGF domain.CD162/PSGL-1 Protein, Mouse (HEK293, His) is the recombinant mouse-derived CD162/PSGL-1 protein, expressed by HEK293 , with C-His labeled tag.

CD162, also known as P-selectin glycoprotein ligand-1 (PSGL-1), functions as an SLe(x)-type proteoglycan and plays a crucial role in the early stages of inflammation by mediating rapid leukocyte rolling over vascular surfaces through high-affinity, calcium-dependent interactions with E- and P-selectins. This interaction is pivotal for the initial capture of leukocytes. CD162 forms homodimers linked by disulfide bonds and interacts with P- and E-selectins through their lectin/EGF domains. For high-affinity binding to P-selectin, sialyl Lewis X glycan modification and tyrosine sulfation, likely on Tyr-54, are required. Dimerization appears dispensable for P-selectin binding. Additionally, CD162 interacts with sorting nexin 20 (SNX20) and mediates SYK activation downstream of P-selectin/SELP binding. Furthermore, CD162 interacts with moesin (MSN) and spleen tyrosine kinase (SYK), contributing to downstream signaling events. It also engages with HAVCR1, revealing its involvement in diverse cellular interactions.
