GlycoFlux™ Human SIGLEC1 Overexpression HEK293 Cell Line (CAT#: GLJF-0925-JF840)

Description	GlycoFlux™ human SIGLEC1 overexpression HEK293 cell line is a stable cell line engineered to express SIGLEC1, an immunoglobulin superfamily lectin-like adhesion receptor that binds glycoconjugate ligands in a sialic acid-dependent manner. Normally expressed by a subset of macrophages, SIGLEC1 plays key roles in mediating cell-cell interactions and immune recognition. It is implicated in multiple disease processes and microbial infections, with evidence showing that SIGLEC1 enhances SARS-CoV-2 infection by facilitating viral attachment. This model provides a valuable platform for dissecting sialic acid-dependent immune regulation, host-pathogen interactions, and glycosylation-driven adhesion biology.

Summary	This gene encodes a protein from the immunoglobulin superfamily, which functions as a lectin-like adhesion molecule, binding glycoconjugate ligands on cell surfaces in a sialic acid-dependent manner. It is a type I transmembrane protein expressed by a subpopulation of macrophages, playing a critical role in cell-cell interactions. The protein is involved in a variety of human diseases and infections, and it has been shown to enhance SARS-CoV-2 infection.
