Abstract:Summary
Prestin (Slc26a5) is a motor protein previously considered to be expressed exclusively in outer hair cells (OHCs) of the inner ear. However, we recently identified the functional expression of prestin in the heart. Nonlinear capacitance (NLC) measurement in OHCs is used to evaluate the signature function of prestin, which exhibits membrane potential-dependent conformational changes. Here, we describe detailed recording techniques and quantification methods for NLC to evaluate the prestin fun… Show more
