Summary
This study introduces five laboratory experiments using bacterial single-stranded DNA binding protein (SSB) to explore protein-DNA and protein-protein interactions. A gamified approach enhanced student learning and confidence in molecular biology techniques.
Area of Science:
- Molecular Biology
- Biochemistry
- Genetics
Background:
- Proteins require interactions with cellular components for function.
- Bacterial single-stranded DNA binding protein (SSB) serves as a model system.
- Characterizing protein-DNA and protein-protein interactions is crucial in molecular biology.
Purpose of the Study:
- To develop and assess a series of five laboratory experiments for characterizing protein interactions.
- To evaluate the impact of a gamification approach on student engagement and learning.
- To provide flexible experimental modules for integration into various courses.
Main Methods:
- Electrophoretic mobility shift assays (EMSA)
- Yeast two-hybrid assays
- Far Western blotting
- Chromatin immunoprecipitation (ChIP)
- Fluorescence microscopy
- Gamification for student engagement
Main Results:
- Students demonstrated increased content knowledge and confidence in molecular biology topics.
- Hands-on laboratory exercises were ranked as the most valuable course component.
- Over 50% of students expressed willingness to take another gamified course.
Conclusions:
- The developed laboratory experiments effectively teach protein interaction characterization.
- Gamification is a successful strategy for enhancing student participation and learning in laboratory courses.

Single-Strand DNA Binding Proteins

For successful DNA replication, the unwinding of double-stranded DNA must be accompanied by stabilization and protection of the separated single strands of the DNA. This crucial task is performed by single-strand DNA-binding (SSB) proteins. They bind to the DNA in a sequence-independent manner, which means that the nitrogenous bases of the DNA need not be present in a specific order for binding of SSB proteins to it. The binding of SSB proteins straightens single-stranded DNA (ssDNA) and makes...

Protein-protein Interfaces
14.4K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Protein Networks
4.4K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

DNA Helicases
23.7K
DNA unwinding helicase enzymes are a type of motor protein. Motor proteins can translocate along filaments or polymers using energy generated from ATP hydrolysis. Helicases are involved in all the important cellular processes where DNA unwinding is required, such as DNA replication, repair, recombination, and transcription. They are present in all living organisms, but vary in their structure, function, and mechanism of action. For example, in prokaryotes, DnaB helicase binds and translocates...
