Hair is a unique structure, characteristic of mammals, controlling body homeostasis, as well as cell and tissue integration. Previous studies in dog, mouse, and rat have identified polymorphisms in Keratin 71 (KRT71) as responsible for the curly/wavy phenotypes. The coding sequence and the 3′ UTR of KRT71 were directly sequenced in randomly bred and(More)
Energized submitochondrial particles were subjected to high or low [3H]ATP/[3H]ADP ratios, maintained during steady state by a pyruvate kinase or hexokinase regenerating system, respectively. Under both steady state conditions, about 1.4 mol [3H]nucleotide/mol ATPase was retained but considerably more [3H]ATP was retained with the high [3H]ATP/[3H]ADP(More)
The gene 1.2 protein of bacteriophage T7, a protein required for phage T7 growth on Escherichia coli optA1 strains, has been purified to apparent homogeneity and shown to restore DNA packaging activity of extracts prepared from E. coli optA1 cells infected with T7 gene 1.2 mutants (Myers, J. A., Beauchamp, B. B., White, J. H., and Richardson, C. C. (1987)(More)
Gene 1.2 of bacteriophage T7, located near the primary origin of DNA replication at position 15.37 on the T7 chromosome, encodes a 10,059-dalton protein that is essential for growth on Escherichia coli optA1 strains (Saito, H., and Richardson, C. C. (1981) J. Virol. 37, 343-351). In the absence of the T7 1.2 and E. coli optA gene products, the degradation(More)
When the filamentous, nitrogen-fixing cyanobacterium Anabaena variabilis ATCC 29413 was subjected to nitrogen starvation under aerobic conditions, a complex series of events was initiated which resulted in heterocyst formation and derepression of the ability to fix dinitrogen. Using DNA-RNA hybridization techniques, we monitored the expression of several(More)
Intramolecular base-pairing interactions have been probed in the small nuclear RNA U1 in vivo. HeLa cells were treated with the psoralen derivative aminomethyltrioxsalen, and cross-linking was carried out by irradiating the intact cells with light of 365 nm wavelength. Cross-linking resulted in a discrete shift in electrophoretic mobility of approximately(More)
