SLC25A11

Catalyzes the transport of 2-oxoglutarate (alpha-oxoglutarate) across the inner mitochondrial membrane in an electroneutral exchange for malate. Can also exchange 2-oxoglutarate for other dicarboxylic acids such as malonate, succinate, maleate and oxaloacetate, although with lower affinity (By similarity). Substrate exchange across the membrane occurs consecutively with one substrate being transported first, then dissociating from the substrate binding site before the second substrate binds for transport in the opposite direction. Does not transport glutathione. In addition can facilitate proton transport in the presence of protonophores such as long-chain fatty acids, contributing to mitochondrial uncoupling and regulation of mitochondrial energetic efficiency (By similarity). Contributes to several metabolic processes, including the malate-aspartate shuttle, the oxoglutarate/isocitrate shuttle, gluconeogenesis from lactate, and nitrogen metabolism (By similarity). Maintains mitochondrial fusion and fission events, and the organization and morphology of cristae. Involved in the regulation of apoptosis (By similarity)..
