Immunohistochemical staining (Formalin-fixed paraffin-embedded sections) of human duodenum with APC polyclonal antibody (Cat # PAB30466) shows strong cytoplasmic positivity in glandular cells at 1:50-1:200 dilution.
This gene encodes a tumor suppressor protein that acts as an antagonist of the Wnt signaling pathway. It is also involved in other processes including cell migration and adhesion, transcriptional activation, and apoptosis. Defects in this gene cause familial adenomatous polyposis (FAP), an autosomal dominant pre-malignant disease that usually progresses to malignancy. Disease-associated mutations tend to be clustered in a small region designated the mutation cluster region (MCR) and result in a truncated protein product. [provided by RefSeq
