Ubiquitin Ligases in Cholesterol Metabolism

Diabetes & Metabolism Journal, 2014
To maintain cholesterol homeostasis, the processes of cholesterol metabolism are regulated at multiple levels including transcription, translation, and enzymatic activity. Recently, the regulation of protein stability of some key players in cholesterol metabolism has been characterized.

Loss of E3 Ubiquitin Ligase RINES via CpG Methylation Relieves Suppression of STAT3 and MYC, Facilitating Multiple Tumorigeneses. [PDF]

Adv Sci (Weinh)
Dysregulated protein modifications drive tumorigenesis. RINES, an E3 ubiquitin ligase, represses tumor cell proliferation and metastasis by facilitating RING domain‐dependent, ubiquitin–proteasome‐mediated degradation of STAT3 and MYC, which consequently restrains cancer stemness and oncogenic progression.

MAGE-A cancer/testis antigens inhibit MDM2 ubiquitylation function and promote increased levels of MDM4 [PDF]

, 2015
Melanoma antigen A (MAGE-A) proteins comprise a structurally and biochemically similar sub-family of Cancer/Testis antigens that are expressed in many cancer types and are thought to contribute actively to malignancy.

A Key Role for the Ubiquitin Ligase UBR4 in Myofiber Hypertrophy in Drosophila and Mice

Cell Reports, 2019
Summary: Skeletal muscle cell (myofiber) atrophy is a detrimental component of aging and cancer that primarily results from muscle protein degradation via the proteasome and ubiquitin ligases.

TRIM56 coiled-coil domain structure provides insights into its E3 ligase functions

Computational and Structural Biotechnology Journal, 2023
Protein ubiquitination is a post-translation modification mediated by E3 ubiquitin ligases. The RING domain E3 ligases are the largest family of E3 ubiquitin ligases, they act as a scaffold, bringing the E2-ubiquitin complex and its substrate together to

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

RNF12 X-Linked Intellectual Disability Mutations Disrupt E3 Ligase Activity and Neural Differentiation

Cell Reports, 2018
Summary: X-linked intellectual disability (XLID) is a heterogeneous syndrome affecting mainly males. Human genetics has identified >100 XLID genes, although the molecular and developmental mechanisms underpinning this disorder remain unclear.

Ubiquitin Ligation without a Ligase [PDF]

Developmental Cell, 2007
Classically, ubiquitination requires three enzymes acting in sequence: E1, E2, and E3. E3 ubiquitin ligases typically provide substrate specificity. An article in Molecular Cell (Hoeller et al., 2007) now describes the E3-independent monoubiquitination of certain proteins. The mechanism has interesting parallels to SUMO ligation.
