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. Note: This description may include information from UniProtKB.
Protein type: Cell adhesion; Motility/polarity/chemotaxis; Membrane protein, integral; Immunoglobulin superfamily
LTP: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
