Cloning and expression of murine lymphotoxin cDNA. 1987

C B Li, and P W Gray, and P F Lin, and K M McGrath, and F H Ruddle, and N H Ruddle

The murine lymphotoxin (LT) gene has been cloned and used to identify cDNA clones in a library prepared from activated murine T cell mRNA. A recombinant murine genomic library was screened with a human lymphotoxin cDNA probe, resulting in the isolation of the entire LT gene. The murine LT gene structure is similar to the human gene, containing three intervening sequences. An activated murine T cell cDNA library was prepared with poly(A)+ RNA isolated 7 hr after concanavalin A stimulation of an L3T4+ interleukin 2-dependent murine T cell clone. Two colonies of the cDNA library that contained inserts that hybridized with the murine LT gene probe were sequenced and were used to construct expression plasmids. The amino acid sequence deduced from the cDNA indicates that murine LT is highly homologous to human LT (74%) and is related to murine tumor necrosis factor (35% homology). The cDNA was transcribed and was translated in vitro, and was expressed in COS-1 cells. This has resulted in the production of LT biological activity.

UI MeSH Term Description Entries
D008233 Lymphotoxin-alpha A tumor necrosis factor family member that is released by activated LYMPHOCYTES. Soluble lymphotoxin is specific for TUMOR NECROSIS FACTOR RECEPTOR TYPE I; TUMOR NECROSIS FACTOR RECEPTOR TYPE II; and TUMOR NECROSIS FACTOR RECEPTOR SUPERFAMILY, MEMBER 14. Lymphotoxin-alpha can form a membrane-bound heterodimer with LYMPHOTOXIN-BETA that has specificity for the LYMPHOTOXIN BETA RECEPTOR.

D011061 Poly A A group of adenine ribonucleotides in which the phosphate residues of each adenine ribonucleotide act as bridges in forming diester linkages between the ribose moieties. Adenine Polynucleotides,Polyadenylic Acids,Poly(rA),Polynucleotides, Adenine
D003001 Cloning, Molecular The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells. Molecular Cloning
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D004274 DNA, Recombinant Biologically active DNA which has been formed by the in vitro joining of segments of DNA from different sources. It includes the recombination joint or edge of a heteroduplex region where two recombining DNA molecules are connected.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
