Mouse thymidine kinase: the promoter sequence and the gene and pseudogene structures in normal cells and in thymidine kinase deficient mutants.
The mouse genome carries one gene and two pseudogenes for cytoplasmic thymidine kinase. The overall structure of these genes was determined with the help of cosmids and lambda phage clones and the upstream sequence containing the promoter was determined. The data allow an allocation of bands seen in the complex patterns of genomic Southern blots obtained from the DNA of wild type cells and of t...
متن کاملPersistence of thymidine kinase activity in mitochondria of a thymidine kinase-deficient derivative of mouse L cells.
The cell line LM(TK(-)) Cl 1D, a derivative of mouse L fibroblasts deficient in thymidine kinase (EC 2.7.1.21) that shows very little thymidine kinase activity in extracts of whole cells as compared to the parental line, and that does not incorporate thymidine or 5-bromodeoxyuridine into nuclear DNA, has maintained the capacity to incorporate these precursors into mitochondrial DNA at a substan...
متن کاملMolecular evolution of mammalian lactate dehydrogenase-A genes and pseudogenes: association of a mouse processed pseudogene with a B1 repetitive sequence.
A mouse genomic clone containing a lactate dehydrogenase-A (LDH-A) processed pseudogene and a B1 repetitive element was isolated, and a nucleotide sequence of approximately 3 kb was determined. The pseudogene and B1 element are flanked by perfect 13-bp repeats, and the B1 sequence starts at 14 nucleotides 3' to the presumptive polyadenylation signal of the pseudogene. The nucleotide sequences o...
متن کاملEnrichment of processed pseudogene transcripts in L1-ribonucleoprotein particles.
Long INterspersed Elements (LINE-1s, L1s) are responsible for over one million retrotransposon insertions and 8000 processed pseudogenes (PPs) in the human genome. An active L1 encodes two proteins (ORF1p and ORF2p) that bind with L1 RNA and form L1-ribonucleoprotein particles (RNPs). Although it is believed that the RNA-binding property of ORF1p is critical to recruit other mobile RNAs to the ...
متن کاملAcquisition of Chick Cytosol Thymidine Kinase Activity by Thymidine Kinase-deficient Mouse Fibroblast Cells after Fusion with Chick Erythrocytes
Chick-mouse heterokaryons were obtained by UV-Sendai virus-induced fusion of chick erythrocytes with thymidine (dT) kinase-deficient mouse fibroblast [LM(TK(-))] cells. Autoradiographic studies demonstrated that 1 day after fusion, [(3)H]dT was incorporated into both red blood cell and LM(TK(-)) nuclei of 23% of the heterokaryons. Self-fused LM(TK(-)) cells failed to incorporate [(3)H]dT into n...
