LIGHT, also known as TNFSF14, HVEML and CD258, is a cytokine that belongs to the tumor necrosis factor (TNF) superfamily. LIGHT is a single-pass type II transmebrane glycoprotein consisting of a 37 amino acid (aa) cytoplasmic domain, a 21-aa transmembrane domain (TM) and a 182 aa extracellular domain (ECD). LIGHT is expressed by activated T lymphocytes, monocytes, granulocytes, spleen cells, and immature dendritic cells. LIGHT is known to bind at lest 2 TNF receptor superfamily (TNFRSF) members: HVEM, which is predominantly expressed by T cells, and LTβR (lymphotoxin β receptor), which is expressed by stromal cells and nonlymphoid hematopoietic cells. LIGHT also binds to a soluble TNFRSF member, DcR3 (decoy receptor 3), which can modulate the function of LIGHT. LIGHT functions as a co-stimulatory factor for the activation of lymphoid cells and as a deterrent to infection by herpesvirus. LIGHT activates NF-kappaB, stimulates the proliferation of T cells, and triggers apoptosis of various tumor cells. LIGHT is also reported to prevent TNF-mediated apoptosis in primary hepatocyte. LIGHT has been shown to suppress tumor formation through the up-regulation of intercellular adhesion molecule 1 and the increase of lymphocyte adhesion to cancer cells. LIGHT is thus a promising target for cancer treatment.

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.
