Deterministic Model Of The Voltage Dependent Anion Channel (Vdac) Kinetics, Viren Shah

Theses and Dissertations

The voltage-dependent anion channel (VDAC) is a voltage gated channel residing on the outer mitochondrial membrane (OMM) that facilitates the flow of metabolites between the cytosol and mitochondria. The channel is regulated through conformational changes driven by electrostatic effects along with numerous regulatory mechanisms. The aim of this study is to mechanistically model kinetics of substrate flow through VDAC and incorporate them into existing mechanistic computational models of mitochondrial function. The resulting model is used in two ways: 1) to establish mitochondrial bioenergetics (conductance, permeability, and current/flux) under physiological conditions, and 2) to conduct perturbations simulating the effect of altered …
