Summary
Steroid hormone receptors are modified by various post-translational modifications (PTMs), impacting their function. Understanding these PTMs is key to developing improved therapeutic ligands.
Area of Science:
- Molecular Endocrinology
- Gene Regulation
- Cellular Signaling
Background:
- Steroid hormones regulate numerous physiological functions.
- Steroid receptors act as ligand-activated transcription factors.
- Cofactors modulate gene expression by altering chromatin structure.
Purpose of the Study:
- To review the post-translational modifications (PTMs) of steroid receptors.
- To explore the impact of PTMs on receptor stability and activity.
- To highlight the potential for developing novel ligands based on PTM understanding.
Main Methods:
- Literature review of studies on steroid receptor modifications.
- Analysis of identified post-translational modifications including phosphorylation, acetylation, ubiquitylation, and sumoylation.
- Examination of the functional consequences of these modifications.
Main Results:
- Steroid receptors undergo diverse PTMs beyond phosphorylation.
- Acetylation, ubiquitylation, and sumoylation are evidenced on steroid receptors.
- PTMs influence receptor stability, activity, and gene-specific regulation.
Conclusions:
- Post-translational modifications are critical regulators of steroid receptor function.
- Further understanding of PTMs offers avenues for novel therapeutic ligand development.
- Targeting PTMs may lead to improved clinical profiles for steroid-based therapies.

01:31Transducer Mechanism: Nuclear Receptors
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:

02:04Covalently Linked Protein Regulators
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.
These groups modify specific amino acids in a protein.

01:45Regulation of Nuclear Protein Sorting
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...
01:31Internal Receptors
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.
01:26Signal Transduction: Overview
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.
Typically, signal transduction involves three...

Many cellular signals are hydrophilic and cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind intracellular receptors that reside within the cell cytoplasm or nucleus. Many mammalian steroid hormones and nitric oxide (NO) gas use this cell signaling mechanism.
