Human C-Type Lectin Domain Family 10 Member A / CD301 (CLEC10A) Protein

Background

CLEC10A (C-type lectin domain containing 10A), also known as CD301 or MGL (Macrophage Galactose-Type Lectin), is a transmembrane protein in the C-type lectin receptor (CLR) family primarily expressed on antigen-presenting cells such as dendritic cells, macrophages, and certain monocytes. CLEC10A is part of the innate immune system, specializing in recognizing carbohydrate structures on the surfaces of cells and pathogens. Specifically, it binds to terminal galactose and N-acetylgalactosamine (GalNAc) residues, making it essential for identifying certain pathogens and interacting with glycoproteins on cellular surfaces. CLEC10A’s specificity for galactose-containing glycans allows it to function in immune surveillance, pathogen clearance, and immunomodulation, making it a focal point in immune-related research. Its expression on dendritic cells and macrophages positions it to play a key role in the innate immune system's interactions with the adaptive immune response, particularly in tissue immune environments. CLEC10A’s involvement in recognizing glycosylated antigens has implications for disease processes, including infections, cancer, and autoimmune conditions.
