CD27 is a single-pass, type I transmembrane glycoprotein in the TNF receptor superfamily (TNFRSF7).  CD27 is expressed as a disulfide­linked homodimer on the cell surface. Proteolytic cleavage of CD27 results in the shedding of a 28­32 kDa fragment of the extracellular domain (ECD) with three TNFR cysteine­rich repeats.  The expression of CD27 is limited to cells of the lymphoid lineage.  CD27 is weakly expressed on naïve T cells and NK cells and is up­regulated upon cell activation. It is also up­regulated on activated germinal center B cells, plasma cells, and a subset of memory B cells.  CD27 acts as a co­stimulatory molecule that supports lymphocyte activation and survival. As a T and B cell co-stimulatory molecule, the activity of CD27 is governed by a TNF-like ligand CD70 on lymphocytes and dendritic cells. CD27 binds to the transmembrane glycoprotein CD70 that is expressed on activated B cells, activated T cells, and dendritic cells.  CD27 transduces signals and subsequently leads to the activation of NF-κB and JNK pathways that contribute to the activation and survival of T cells and NK cells as well as the long-term maintenance of T cell immunity. CD27 also plays a key role in regulating B-cell differentiation, activation and immunoglobulin synthesis. Ligation of CD27 on B cells promotes germinal center formation and the expansion and affinity maturation of memory B cell responses. Mutations in the CD27 gene are associated with an autosomal recessive immunodeficiency disorder, lymphoproliferative syndrome 2 (LPFS2).

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’-CGGGAAGCAATAGCATGATA-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.
