CEACAM1, also known as carcinoembryonic antigen-related cell adhesion molecule 1 isoform 6, is a member of the carcinoembryonic antigen (CEA) gene family which belongs to the immunoglobulin superfamily. This protein is a surface glycoprotein expressed on various blood cells, epithelial cells, and vascular cells. It performs actions in multiple cellular processes including tissue differentiation, angiogenesis, apoptosis, metastasis, as well as the modulation of innate and adaptive immune responses. Source: Recombinant protein corresponding to aa35-428 from human CEACAM1, fused to His-Tag at C-terminal, expressed in insect cell. Molecular Weight: ~44.6kD (405aa), ~40-70kD (SDS-PAGE under reducing conditions.)
