The Arabidopsis gene GF14 lambda that encodes a 14-3-3 protein was introduced into cotton plants to explore the physiological roles that GF14 lambda might play in plants. The expression level of GF14 lambda under the control of the cauliflower mosaic virus 35S promoter varied in transgenic cotton plants, and lines that expressed GF14 lambda demonstrated a(More)
The acidic enamel protein tuftelin has now been cDNA cloned, sequenced and characterized in a number of vertebrate species. Recently, the bovine tuftelin gene structure was elucidated. Cloning of the human tuftelin gene and partial sequencing of a number of exons have also been achieved. Immunologically, the protein has been shown to be conserved throughout(More)
Tuftelin has been suggested to play an important role during the development and mineralization of enamel, but its precise function is still unclear. This article reviews major milestones in the discovery, structural characterization, expression, localization, and conservation of tuftelin in different vertebrate species. It focuses on the structure of the(More)
Tuftelin has been suggested to play an important role during the development and mineralization of enamel. We isolated the full-length human tuftelin cDNA using reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (5' RACE and 3' RACE) methods. Sequence analysis of the tuftelin cDNA revealed an open reading frame of(More)
RT-PCR, Southern blotting and DNA sequencing have established for the first time that tuftelin mRNA is expressed in human ameloblastoma tumor. The expression of amelogenin mRNA in ameloblastoma was also established, confirming earlier reports by Snead et al. These results corroborate, on a molecular level, the enamel organ epithelial origin of(More)
