Histone crosstalk directed by H2B ubiquitination is required for chromatin boundary integrity [PDF]
Genomic maps of chromatin modifications have provided evidence for the partitioning of genomes into domains of distinct chromatin states, which assist coordinated gene regulation.

The MEKK1 PHD ubiquitinates TAB1 to activate MAPKs in response to cytokines. [PDF]
Unlike the other MAP3Ks, MEKK1 (encoded by Map3k1) contains a PHD motif. To understand the role of this motif, we have created a knockin mutant of mouse Map3k1 (Map3k1(m) (PHD)) with an inactive PHD motif.

In this chapter, we describe a method for detecting the ubiquitination status of G protein-coupled receptors (GPCRs). This involves co-expression of a GPCR with an epitope-tagged ubiquitin construct in a -heterologous mammalian expression system. Stimulus-dependent modification of the GPCR by -ubiquitin is detected by immunoprecipitation and subsequent

Using Ubiquitin Binders to Decipher the Ubiquitin Code [PDF]
Post-translational modifications (PTMs) by ubiquitin (Ub) are versatile, highly dynamic, and involved in nearly all aspects of eukaryote biological function. The reversibility and heterogeneity of Ub chains attached to protein substrates have complicated their isolation, quantification, and characterization.

PKC-Dependent GlyT1 Ubiquitination Occurs Independent of Phosphorylation: Inespecificity in Lysine Selection for Ubiquitination. [PDF]
Neurotransmitter transporter ubiquitination is emerging as the main mechanism for endocytosis and sorting of cargo into lysosomes. In this study, we demonstrate PKC-dependent ubiquitination of three different isoforms of the glycine transporter 1 (GlyT1).

The roles of protein ubiquitination in tumorigenesis and targeted drug discovery in lung cancer
The malignant lung cancer has a high morbidity rate and very poor 5-year survival rate. About 80% - 90% of protein degradation in human cells is occurred through the ubiquitination enzyme pathway.

ALIX binds a YPX(3)L motif of the GPCR PAR1 and mediates ubiquitin-independent ESCRT-III/MVB sorting. [PDF]
The sorting of signaling receptors to lysosomes is an essential regulatory process in mammalian cells. During degradation, receptors are modified with ubiquitin and sorted by endosomal sorting complex required for transport (ESCRT)-0, -I, -II, and -III ...

A Ubiquitin-like Protein Unleashes Ubiquitin Ligases [PDF]
Modification of cullin-RING ubiquitin ligases by the ubiquitin-like molecule Nedd8 promotes substrate ubiquitination. A crystal structure of a cullin modified by Nedd8 recently reported in Cell (Duda et al., 2008) and a biochemical study in Molecular Cell (Saha and Deshaies, 2008) reveal the dramatic impact on the ligase machinery by conjugation of ...

Ubiquitination and SUMOylation, which are posttranslational modifications, play prominent roles in regulating both protein expression and function in cells, as well as various cellular signal transduction pathways. Metabolic reprogramming often occurs in

Regulation of Wnt Signaling through Ubiquitination and Deubiquitination in Cancers
The Wnt signaling pathway plays important roles in embryonic development, homeostatic processes, cell differentiation, cell polarity, cell proliferation, and cell migration via the β-catenin binding of Wnt target genes.
