Prestin-prestin and prestin-GLUT5 interactions in HEK293T cells.
The remarkable hearing sensitivity and frequency selectivity in mammals is attributed to cochlear amplifier in the outer hair cells (OHCs). Prestin, a membrane protein in the lateral wall of OHC plasma membrane, is required for OHC electromotility and cochlear amplifier. In addition, GLUT5, a fructose transporter, is reported to be abundant in the plasma membrane of the OHC lateral wall and has...
متن کاملAnalysis of the oligomeric structure of the motor protein prestin.
Prestin, a member of the solute carrier family 26, is expressed in the basolateral membrane of outer hair cells. This protein provides the molecular basis for outer hair cell somatic electromotility, which is crucial for the frequency selectivity and sensitivity of mammalian hearing. It has long been known that there are abundantly expressed approximately 11-nM protein particles present in the ...
متن کاملSyndecan-1 amplifies angiotensin II-induced cardiac fibrosis.
Syndecan-1 (Synd1) is a transmembrane heparan sulfate proteoglycan that functions as a coreceptor for various growth factors and modulates signal transduction. The present study investigated whether Synd1, by affecting growth factor signaling, may play a role in hypertension-induced cardiac fibrosis and dysfunction. Expression of Synd1 was increased significantly in mouse hearts with angiotensi...
متن کاملStructural rearrangements of the motor protein prestin revealed by fluorescence resonance energy transfer.
Prestin is a membrane protein expressed in the outer hair cells (OHCs) in the cochlea that is essential for hearing. This unique motor protein transduces a change in membrane potential into a considerable mechanical force, which leads to a cell length change in the OHC. The nonlinear capacitance in cells expressing prestin is recognized to reflect the voltage-dependent conformational change of ...
متن کاملExpression of prestin, a membrane motor protein, in the mammalian auditory and vestibular periphery.
Hair cells are specialized mechanoreceptors common to auditory and vestibular sensory organs of mammalian and non-mammalian species. Different hair cells are believed to share common features related to their mechanosensory function. It has been shown that hair cells possess various forms of motile properties that enhance their receptor function. Membrane-based electromotility is a form of hair...
