Transposons

Transposons

Transposons, or "jumping genes," are small mobile genetic elements (MGEs) that range from 700 to 40,000 base pairs in length. They are found in all organisms and can move within the same chromosome or transfer to different chromosomes. In some cases, transposons can also jump between different host DNA molecules, such as plasmids or viruses, contributing to genetic variability.Barbara McClintock first discovered these mobile genetic elements in the 1940s while studying maize genetics, and she...

Inhibitors of Viral Protein Synthesis

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...

Antiviral Nucleoside Inhibitors

Antiviral Nucleoside Inhibitors

Antiviral Nucleoside InhibitorsAntiviral nucleoside inhibitors are structural analogs of natural nucleosides that interfere with viral DNA or RNA synthesis. These compounds selectively target viral polymerases due to their resemblance to host nucleosides, thereby disrupting viral genome replication.Mechanism of Acyclovir ActionAcyclovir is a guanosine analog with a three-carbon acyclic side chain. It selectively targets herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2),...

DNA-only Transposons

DNA-only Transposons

DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
The donor site from where the transposon is excised is either degraded or...

Eukaryotic Transcription Inhibitors

Eukaryotic Transcription Inhibitors

Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a DNA...

Translesion DNA Polymerases

Translesion DNA Polymerases

Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...

Background:

Mos1 is a transposon, a mobile genetic element.
Transposons and viral integrases share similarities in their mechanisms.
Inhibiting these enzymes is crucial for understanding genome stability and developing antiviral therapies.

Purpose of the Study:

To identify novel chemical inhibitors of Mos1 transposition.
To explore the potential of Mos1 transposase as a surrogate for screening HIV-1 integrase inhibitors.

Main Methods:

Chemical synthesis of novel compounds based on a bis-(heteroaryl)maleimides scaffold.
Assay of compound activity against Mos1 transposition.
Evaluation of cross-activity with HIV-1 integrase.

Main Results:

Several known inhibitors of Tn5 transposase and HIV-1 integrase also inhibited Mos1 transposition.
Novel bis-(heteroaryl)maleimides were identified as potent Mos1 inhibitors.
The mechanism of action varied based on chemical substitutions on the maleimide scaffold.
Significant cross-activity was observed between HIV-1 integrase and Mos1 transposase inhibition.

Conclusions:

Mos1 transposase can be effectively inhibited by small molecules.
Bis-(heteroaryl)maleimides represent a promising scaffold for developing Mos1 inhibitors.
Mos1 transposase serves as a valuable surrogate for high-throughput screening of HIV-1 integrase inhibitors, potentially accelerating antiviral drug discovery.
