3 Single channel permeation of the larger GSH anion was low but detectable (P(Na)/P(GSH) ~12 for Cx46 and ~8 for Cx50), whereas permeation of divalent anion glutathione disulfide (GSSG) was undetectable. Glutathione gap junction protein, alpha 3 Mus musculus
4 Single channel permeation of the larger GSH anion was low but detectable (P(Na)/P(GSH) ~12 for Cx46 and ~8 for Cx50), whereas permeation of divalent anion glutathione disulfide (GSSG) was undetectable. Glutathione gap junction protein, alpha 3 Mus musculus
5 Measurement of GSH levels in the lenses from connexin knock-out (KO) mice indicated Cx46, and not Cx50, is necessary for transport of GSH to the core. Glutathione gap junction protein, alpha 3 Mus musculus
6 Levels of GSH in the nucleus were markedly reduced in Cx46 KO, whereas they were unaffected by Cx50 KO. Glutathione gap junction protein, alpha 3 Mus musculus
7 These results indicate that glutathione diffuses from cortical fiber cells to the nucleus via gap junction channels formed by Cx46. Glutathione gap junction protein, alpha 3 Mus musculus
