The carcinoembryonic-antigen-related cell-adhesion molecule (CEACAM) family of proteins has been implicated in various intercellular-adhesion and intracellular-signalling-mediated effects that govern the growth and differentiation of normal and cancerous cells. CEACAM1 , also known as biliary glycoprotein I (BGP I) and CD66a , is a member of the carcinoembryonic antigen (CEA) gene family which belongs to the immunoglobulin superfamily. The highly glycosylated CEACAM1 contains one N-terminal V-type Ig-like domain and three C2-type Ig-like domains within its ECD , and one ITIM motif and a calmodulin binding site in the cytoplasmic region. CEACAM1 is a surface glycoprotein expressed on various blood cells , epithelial cells , and vascular cells. It was described as an adhesion molecule mediating cell adhesion via both homophilic and heterophilic manners , and was detected on leukocytes , epithelia , and endothelia. Studies have revealed that CEACAM1 performs actions in multiple cellular processes including tissue differentiation , angiogenesis , apoptosis , metastasis , as well as the modulation of innate and adaptive immune responses.
Stoccaggio: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.
