Entrez gene summary

The Lewis histo-blood group system comprises a set of fucosylated glycosphingolipids that are synthesized by exocrine epithelial cells and circulate in body fluids. The glycosphingolipids function in embryogenesis, tissue differentiation, tumor metastasis, inflammation, and bacterial adhesion. They are secondarily absorbed to red blood cells giving rise to their Lewis phenotype. This gene is a member of the fucosyltransferase family, which catalyzes the addition of fucose to precursor polysaccharides in the last step of Lewis antigen biosynthesis. It encodes an enzyme with alpha(1,3)-fucosyltransferase and alpha(1,4)-fucosyltransferase activities. Mutations in this gene are responsible for the majority of Lewis antigen-negative phenotypes. Multiple alternatively spliced variants, encoding the same protein, have been found for this gene. [provided by RefSeq, Jul 2008]

Staining summary

Normal tissues displayed weak to moderate cytoplasmic staining with additional nuclear positivity in small intestine, Purkinje cells, squamous epithelia and testis. Membranous staining was observed in stomach, bronchus and glandular cells of uterus. Small intestine and cells in granular layer of cerebellum exhibited strong immunoreactivity. Adrenocortical cells, hematopoietic tissue, breast, glial cells, liver, prostate and most of the lymphoid tissue were negative.
