  • solute carrier family 25 mitochondrial, citrate
  • CATEGORY transport carrier
    SUBCELLULAR LOCALIZATION     intracellular
  • essential component of the shuttle system which transports acetyl-CoA from mitochondria to the cytosol where lipogenesis occurs
  • basic FUNCTION
  • involved in the citrate H+ /malate exchange, important for the bioenergetics of hepatic cells
  • plays a regulatory role in glucose-stimulated insulin secretion
  • having a role in the regulation of chromosome integrity
  • required to prevent chromosome breaks (link between citrate metabolism, chromatin acetylation and chromosome integrity)
  • catalyses the efflux of citrate from the mitochondrial matrix in exchange for cytosolic malate
  • has a critical role in inflammation
  • works with other factors in the regulation of sperm energy metabolism to sustain capacitation process and acrosome reaction
  • maintains mitochondrial homeostasis in metabolically active, high proliferating tissues
