A new antibody to monoubiquitinated histone H2B ... In yeast, mutations in the ubiquitin target sites have shown that mono-ubiquitination of histone H2B at Lys120 is an important signal for ...

Frizzled (FZD) proteins are the principal receptors of the Wnt signaling pathway. However, whether Wnt ligands induce FZD endocytosis and degradation remains elusive. The transmembrane E3 ubiquitin ...
