... implying that Ddx 3x in fact displays normal X inactivation in neonatal mouse brain. The discrepancy could be du e to tissue-specificity of X inactivation, or spurious expression effects resulting from ... allele-specific expression of 35 genes by pyrosequencing Thirty-three X- linked genes (Ctps2, Plxna3, Syn1, Phf6, Taf1, Utx, Syap1, Maoa, Zfx, Xist, Usp 9x, Ddx 3x, Ikbkg,...

Interestingly, Xist-induced ... escaping X inactivation have already lost their corres ponding Y copy. is suggests either that establish- ment of X inactivation may lag behind Y degeneration, or that sp...

... coenzyme M. Mutations in His237 or Cys239, which are proposed to be involved in ligating zinc, resulted in an over 90% loss in enzyme activity and in distinct changes in the zinc ligands. In the His237 ... MtaA is a zinc protein that catalyzes the methylation of coenzyme M (HS-CoM) with methylcob(III)alamin. We report zinc XAFS (X- ray absorption fine structure) results indicatin...
