Anti-CEACAM1 Antibody, clone 11-1H

The carcinoembryonic antigen- (CEA-) related cell adhesion molecules (CEACAMs) constitute a 12-member subgroup of the CEA family of immunoglobulin-related proteins first described in 1965 (PMID 4953873). CEACAMs are reported to participate in diverse physiological processes, including cell adhesion, differentiation, proliferation, and survival, as well as in carcinogenesis and bacterial pathogenesis. CEACAM molecules from neighbouring cells can interact via their respective extracellular N-terminal IgV-like domain and mediate cell-cell adhesion through trans-oligomerization. CEACAM molecules within the same cell can also undergo transmembrane domain-mediated cis-oligomerization, an event important for sustaining downstream cellular signaling. Athough CEACAM1 is shown to utilize its cytoplasmic domain for transducing cellular signaling, not all CEACAM members are expressed with a significant cytoplasmic domain, and others (CEACAM5/6/7/8) are GPI-anchored without even a transmembrane domain. (PMID 4735478). Rodent Ceacam1 (also known as C-CAM 105, Cell-CAM 105, Ecto-ATPase, GP110, pp120; UniProt P16573) is encoded by the Ceacam1 gene (NCBI Gene ID 81613). As is the case with its human counterpart (P13688), there exisit a long (canonical; 519aa) and a short (458aa) form with a reduced cytoplamic domain as a result of alternate splicing. An additional 10 splice variants are also reported for human CEACAM1. Clone 11-1H does not cross-react with human CEACAM1/3/4/5/6/7/8 or mouse CEACAM1/2.

Recombinant protein corresponding to the extracellular, excluding N domain of rat CEACAM1.
