Summary
SUMOylation of nuclear receptors regulates cell metabolism and physiological functions. This post-translational modification offers potential therapeutic targets for metabolic and inflammation-related diseases like atherosclerosis and tumors.
Area of Science:
- Molecular Biology
- Cellular Metabolism
- Biochemistry
Background:
- Nuclear receptors are crucial ligand-activated transcription factors involved in cell metabolism and disease.
- They undergo post-translational modifications including SUMOylation, ubiquitination, phosphorylation, and acetylation.
- Interactions between these modifications impact metabolic and physiological processes.
Purpose of the Study:
- To review the function of SUMOylation in nuclear receptors.
- To highlight the role of SUMOylation in regulating nuclear receptor activity.
- To explore the implications of SUMOylation for metabolic and inflammation-related diseases.
Main Methods:
- Literature review of studies on nuclear receptor SUMOylation.
- Analysis of the regulatory mechanisms of SUMOylation on nuclear receptor function.
- Synthesis of information on the involvement of SUMOylated nuclear receptors in disease.
Main Results:
- SUMOylation significantly impacts nuclear receptor function and cellular metabolism.
- Crosstalk between SUMOylation and other modifications (ubiquitination, phosphorylation, acetylation) is critical.
- SUMOylated nuclear receptors are implicated in lipid metabolism, inflammation, bile acid homeostasis, and autophagy.
Conclusions:
- SUMOylation is a key regulator of nuclear receptor activity and cell metabolism.
- Dysregulation of SUMOylation in nuclear receptors contributes to diseases such as atherosclerosis and cancer.
- Targeting SUMOylation of nuclear receptors presents a promising therapeutic strategy for metabolic and inflammatory disorders.

2.1K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

01:45Regulation of Nuclear Protein Sorting
3.0K
Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

01:26Signal Transduction: Overview
10.5K
Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.

8.1K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

8.2K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
