Summary
This study reveals that a hypothetical protein from Litorilituus sediminis contains a von Hippel-Lindau (VHL) domain, crucial for tumor suppression. This finding highlights potential applications in cancer research for higher organisms.
Area of Science:
- Microbiology
- Molecular Biology
- Bioinformatics
Background:
- Litorilituus sediminis, a novel bacterium from the Colwelliaceae family, possesses a hypothetical protein with potential tumor suppressor activity.
- The von Hippel-Lindau (VHL) domain is known for its significant role in regulating cellular processes and its association with tumor suppression.
Purpose of the Study:
- To elucidate the structure and function of the hypothetical protein EMK97_00595 (QBG34344.1) from Litorilituus sediminis.
- To investigate the presence and significance of the von Hippel-Lindau (VHL) domain within this protein.
Main Methods:
- Utilized various bioinformatics tools for functional annotation and structural analysis.
- Performed homology searches to identify conserved domains and evolutionary relationships.
Main Results:
- The hypothetical protein was identified as an extracellular secretory soluble signal peptide.
- Confirmed the presence of the von Hippel-Lindau (VHL) beta domain, known for its tumor suppressor functions.
- Demonstrated evolutionary conservation of the VHL domain across diverse organisms, including mammals, insects, and nematodes.
Conclusions:
- The annotated hypothetical protein from Litorilituus sediminis exhibits significant tumor suppressor potential due to its VHL domain.
- This protein's VHL domain plays a critical role in the oxygen-sensing pathway and inhibits cell proliferation and angiogenesis.
- The findings suggest potential relevance for future cancer research in higher organisms.

8.3K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

5.2K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

02:23Abnormal Proliferation
4.7K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

02:26Protein Networks
4.1K
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,...

02:38The Ras Gene
6.5K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
