CLEC4B2 (C-type lectin domain family 4 member B2) is a protein encoded by the CLEC4B2 gene, which belongs to the C-type lectin family. These proteins are characterized by a conserved carbohydrate-recognition domain (CRD) that mediates calcium-dependent binding to glycans, playing critical roles in immune recognition, pathogen sensing, and cell adhesion. CLEC4B2. also referred to as DCIR4 or CLECSF11 in some contexts, is primarily expressed in immune cells, including dendritic cells and myeloid lineages, where it may function as a pattern recognition receptor (PRR) for microbial components or damaged host molecules.
Structurally, CLEC4B2 contains a single extracellular CRD, a transmembrane domain, and a short cytoplasmic tail lacking classical signaling motifs, suggesting potential interactions with adaptor proteins for downstream signaling. Its ligand specificity remains less defined compared to related C-type lectins like Dectin-1 or DC-SIGN, but it is hypothesized to recognize endogenous or exogenous glycans, modulating immune responses such as cytokine production or phagocytosis.
Recombinant CLEC4B2 protein is engineered for research applications, typically produced in mammalian or insect expression systems to ensure proper post-translational modifications. It is used to study ligand-receptor interactions, immune signaling pathways, and its role in diseases like infections, autoimmune disorders, or cancer. Recent studies explore its involvement in viral entry (e.g., HIV) and tumor microenvironments, though functional data remain limited. As a research tool, purified CLEC4B2 aids in elucidating its immunological contributions and potential therapeutic targeting.
