Summary
The LIM-only protein 2 (LMO2) interacts with specific protein structures and domains, revealing its crucial roles in cytoplasmic metabolism and various cancers.
Area of Science:
- Biochemistry
- Molecular Biology
- Bioinformatics
Background:
- LMO2 is a LIM domain protein superfamily member, ubiquitously expressed in various tissues.
- Its known function involves mediating protein-protein interactions, but its interactome and full functional spectrum are unclear.
- Understanding LMO2's interactions is key to elucidating its biological roles.
Purpose of the Study:
- To analyze the protein-protein interaction characteristics of LMO2.
- To identify specific domains and structural features favored by LMO2 interactions.
- To explore the functional implications of LMO2's interactome, particularly in relation to diseases.
Main Methods:
- Yeast two-hybrid assay was employed using LMO2 as bait.
- Bioinformatic analysis of yeast two-hybrid data and related biological information was performed.
- Characterization of LMO2's interactome was conducted.
Main Results:
- LMO2 preferentially interacts with peptides possessing beta-sheet structures and unstable conformations.
- Key interacting domains identified include WD40 repeat, coiled-coil, Ankyrin repeat, Zinc finger, PDZ, and SH3.
- Functions associated with these domains are significantly enriched in several cancer types.
Conclusions:
- A distinct protein interaction pattern for LMO2, based on secondary structure and domain preference, has been identified.
- LMO2's functions are strongly linked to cytoplasmic metabolic pathways.
- The study highlights LMO2's involvement in multiple types of cancer, suggesting potential therapeutic targets.

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,...

Myosins are a family of molecular motor proteins, first identified in the skeletal muscles, where they are responsible for muscle contraction. Along with their role in muscle contraction, these proteins also play a role in the intracellular transport of molecules and vesicles. There are twenty-four classes of myosins based on their domain sequence and organization. Of the twenty-four, six classes (Myosin I, Myosin II, Myosin V, Myosin VI, Myosin VII, and Myosin X) have been well...

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.

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...
