pGEM-T Vector Information

The pGEM-T is 3kb in length, and contains the amplicin resistance gene, conferring selection of the plasmid in E. coli, and the ori site which is the bacterial origin of replication. The plasmid has multiple cloning sites as shown below. The coding sequence was inserted by TA cloning. Many E. coli strains are suitable for the propagation of this vector including JM109, DH5α and TOP10.

pGEM-T Simple Usage Suggestion:

The coding sequence can be easily obtained by digesting the vector with proper restriction enzyme(s). The coding sequence can also be amplified by PCR with M13 primers, or primer pair SP6 and T7.

Background

Toll-like receptor 3 (TLR3) also known as CD283 (cluster of differentiation 283) is a member of the Toll-like receptor family of pattern recognition receptors of the innate immune system. TLR3/CD283 plays a fundamental role in pathogen recognition and activation of innate immunity. TLR3 is a nucleotide-sensing TLR which is activated by double-stranded RNA, a sign of viral infection. TLRs are highly conserved from Drosophila to humans and share structural and functional similarities. They recognize pathogen-associated molecular patterns (PAMPs) that are expressed on infectious agents, and mediate the production of cytokines necessary for the development of effective immunity. The various TLRs exhibit different patterns of expression. This receptor is most abundantly expressed in placenta and pancreas, and is restricted to the dendritic subpopulation of the leukocytes. It recognizes dsRNA associated with viral infection, and induces the activation of NF-kappaB and the production of type I interferons. It may thus play a role in host defense against viruses.
