|title=Significance of tertiary conformation of otoconial matrix proteins - clinical implications.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/21401448
|abstract=Co-option of the enzyme secretory phospholipase A2 (sPLA2) and adoption of tertiary conformation are essential factors in the multifunctionality of otoconin 90 ([[OC90]]) and homologous modulators. To present results of in vitro studies of recombinant otoconial proteins for the understanding of current concepts of biomolecular mechanisms controlling otoconial mineralization. In vitro characterization of recombinant otoconial proteins with respect to crystal growth parameters and solution state behavior. Evaluation by [[HR]]-SEM, micro-Raman, circular dichroism, in combination with molecular modeling of individual domains and whole [[OC90]]. Polymorph selection: recombinant otoconin 22 (rOC22) in vitro selects calcite rather than aragonite, expression of which requires association with an insoluble scaffold most likely provided by Otolin. Alternate folding of rOC22 results in formation of vaterite, the polymorph of primitive fish otoconia and of diseased human otoconia (e.g. Potter's syndrome). Molecular models of [[OC90]] exhibit a surface of uniform negative electrostatic potential, enabling localized supersaturation. We propose that [[OC90]] interacts with Otolin in formation of iso-oriented columns of nano-crystallites, which should ultimately result in assembly of the complex mosaic of native otoconia.
