Recent Advances in Amelogenin Biochemistry
Connective Tissue Research, 1995This paper reviews advances in amelogenin biochemistry in three areas; (i) amelogenin expression; (ii) amelogenin post-translational and post-secretory processing, and (iii) amelogenin structure and function. Recent studies of amelogenin expression have demonstrated that alternative-splicing of mouse amelogenin RNA generates seven distinct mRNAs ...

A heterogeneous population of amelogenin proteins is derived from a single copy of the mouse amelogenin gene. To investigate the one gene--multiple protein enigma, we designed a study to distinguish between alternative splicing and proteolytic cleavage models.

Regulation of Amelogenin Gene Expression
Critical Reviews in Eukaryotic Gene Expression, 1999The X-chromosomal amelogenin gene is expressed at a high level by ameloblast cells within the enamel organ for a short time during tooth development. Therefore, expression is both tooth specific and developmentally regulated. A Y-chromosomal amelogenin gene is also active in human and cow, but has not been detected in mouse.

Molecular Cloning of Bovine Amelogenin cDna
Advances in Dental Research, 1987Molecular cloning of a bovine amelogenin cDNA was accomplished by construction of a cDNA expression library (λgt11 cDNA library) from the bovine ameloblast mRNA and then screening of the library with antibodies to bovine amelogenins. The complete primary structure of an amelogenin was deduced from cloned cDNA.

Biopolymers, 1998
At the secretory stage of tooth enamel formation the majority of the organic matrix is composed of amelogenin proteins that are believed to provide the scaffolding for the initial carbonated hydroxyapatite crystals to grow. The primary objective of this study was to investigate the interaction between amelogenins and growing apatite crystals.

Amelogenin Gene Expression in Porcine Odontoblasts
Journal of Dental Research, 2002Amelogenin is the major organic component in the enamel matrix of developing teeth and plays an important role in enamel biomineralization. Amelogenin has been reported to be a specific secretory product of ameloblasts. In this study, we examined amelogenin gene expression in various cell layers prepared from a porcine permanent tooth germ using ...

Identification of a Suppressor Element in the Amelogenin Promoter
Journal of Dental Research, 2009Amelogenin expression is regulated in a cell-type- specific manner. Investigators have previously identified an enhancer element by using the 5′ flanking sequence of the amelogenin promoter. However, the cell-type-specific regulation of the amelogenin gene remains poorly understood. In some genes, the first intron regulates tissue-specific expression.

An Amelogenin Minigene to Study Alternative Splicing
DNA and Cell Biology, 2006Diversity in gene expression is commonly observed as a result of alternative splicing of RNA transcripts. This is true in the case of amelogenin, one of the enamel matrix proteins. Our hypothesis is that additional amelogenin mRNA transcripts are generated in vivo, but these transcripts have yet to be observed because of the limitations of currently ...

A Review of the Aggregation Properties of a Recombinant Amelogenin
Connective Tissue Research, 1995The present paper reviews some recent data on the aggregation properties of a recombinant amelogenin using dynamic light scattering, transmission electron microscopy, atomic force microscopy, and size exclusion chromatography. It was found that the recombinant amelogenin M179 molecules in solution form spherical monodisperse aggregates (15-20 nm) which
