Eukaryotic Transcription Activators

Eukaryotic Transcription Activators

Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These...

Activation and Inactivation of G Proteins

Activation and Inactivation of G Proteins

Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high...

tRNA Activation

Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

Transducer Mechanism: G Protein–Coupled Receptors

Transducer Mechanism: G Protein–Coupled Receptors

G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.
GPCRs are also called heptahelical,...

Transducer Mechanism: Enzyme-Linked Receptors

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Background:

Th17 cell differentiation is crucial for immunity but its regulatory networks are not fully understood.
Transcriptional networks governing Th17 cells are known, but protein interactions and posttranslational modifications remain largely uncharacterized.

Purpose of the Study:

To identify key regulators of RORγt stability and its impact on Th17 cell differentiation.

Main Methods:

Utilized genomic and transcriptomic analysis to identify regulatory networks.
Investigated the role of deubiquitylating enzyme DUBA in regulating IL-17 production and Th17 cell differentiation.
Assessed the effect of DUBA on the stability of the transcription factor RORγt.

Main Results:

Identified DUBA as a novel deubiquitylating enzyme.
Demonstrated that DUBA acts as a negative regulator of IL-17 production.
Showed that DUBA regulates the stability of RORγt, a master transcription factor for Th17 cells.

Conclusions:

DUBA plays a critical role in controlling Th17 cell differentiation through RORγt stabilization.
This study reveals a novel posttranslational modification mechanism regulating Th17 cell development.
