CEACAM21 (carcinoembryonic antigen (CEA)-related cell adhesion molecule 21) is a single pass type I transmembrane protein of the CEA family of the immunoglobulin superfamily (IgSF). CEA family members are either transmembrane or GPI­-anchored within two subgroups: the CEACAMs and the pregnancy-specific glycoproteins that are used by several bacterial pathogens to bind and invade host cells.  Members of the CEA family consist of a single N domain, with structural similarity to the Ig variable (IgV) domains, followed by a variable number of Ig constant-like 1 (IgC1) and/or 2 (IgC2) domains. In human, 7 CEACAMs have been identified including 3 transmembrane proteins (CEACAM1, 3, 4) and 4 GPI-anchored molecules (CEACAM5-8). Human CEACAM21 contains 1 C2-type Ig-like (IgC2) motifs in the N-terminal 206 aa extracellular domain (ECD), followed by a transmembrane domain (TM) and a 32 aa short cytoplasmic tail. CEACAM21’s function remains unknown.

Product Details

 

Gene Symbol: CEACAM21

 

NCBI Gene ID: 90273

 

Uniprot Entry: Q3KPI0

 

Construct Details: Full length human CEACAM21 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without a selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 882 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
