Mi2β positively regulates the expression of KLF1 and BCL11A in CID cells. (A) Western blot showing a decrease in murine KLF1 and murine BCL11A protein levels after Mi2β knockdown in CID cells. (B) Western blot showing no change in murine KLF1 and murine BCL11A protein levels after MBD2 knockdown in CID cells. (C) Western blot showing no change in murine KLF1 or murine BCL11A in primary adult mouse erythroblasts from MBD2 knockout mice.
