    text
  • nuclear membrane brush border of renal PCT
  • following microglial activation, CLIC1 translocates from cytosol to plasma membrane where it promotes a chloride conductance
  • basic FUNCTION
  • chloride voltage-gated channel regulatory protein
  • regulate fundamental cellular processes including stabilization of cell membrane potential, transepithelial transport, maintenance of intracellular pH, and regulation of cell volume
  • exhibits both nuclear and plasma membrane chloride ion channel activity
  • actin-regulated membrane protein that could modify solute transport at key stages during cellular events such as apoptosis, cell and organelle division and fusion, cell-volume regulation, and cell movement
  • may play a role in the regulation of osteoblastic differentiation from mesenchymal progenitors
  • acting as both a second messenger and an executor during oxidative stress
  • forms oligomers upon oxidation in the presence of the membranes
  • involved in the lymphatic metastasis of tumors
  • important role for CLIC1 in regulating macrophage function through its ion channel activity, suggesting it is a suitable target for the development of anti-inflammatory drug
  • having the ability to spontaneously insert into lipid membranes from a soluble, globular state
