CD66A Antibody – Mouse

CEACAM1: carcinoembryonic antigen-related cell adhesion molecule 1. A cell-cell adhesion molecule that directly associates with annexin II. Has tumor suppressor activity in prostate carcinoma. Belongs to the immunoglobulin superfamily and the CEA family. Abundantly expressed in epithelia, vessel endothelia, trophoblasts, platelets and neutrophilic granulocytes. Also present in many cell types of the immune system such as B cells, T cells, NK cells, macrophages and dendritic cells. Five alternatively spliced isoforms have been described. Two isoforms are type I membrane proteins, while three are secreted.
