Immunoblot assays show the developmental regulation and glycosylation of β4 subunit. (A) The ~38 kDa band was not expressed until postnatal day 7 in wild-type mice. (B) The treatment of the membrane fractions from the P7, P28 and adult brain tissues with glycosidase PNase F (Enz) converted the immunoreactive proteins into a faster migrating species. P0 and P6 show the immunoreactive proteins without changes between the treated and untreated samples. (C) The similar treatment of the membrane fractions from neonatal A53T mice brain tissues converted the ~38 kDa protein into a faster migrating species, but there is no change in the 35 kDa band with or without PNGase F treatment. The + and - signs indicate the treated and untreated samples, respectively. WT: wild-type mice; A53T: PD transgenic mice; Ad: adult wild-type mice.
