Summary
Accurate gene and protein annotation is crucial for cancer research. Our study found incorrect Serine Threonine Kinase 19 (STK19) annotations in major databases, highlighting the need for careful verification.
Area of Science:
- Genomics
- Cancer Biology
- Bioinformatics
Background:
- Advanced sequencing identifies potential cancer driver mutations.
- Manual curation and analysis of gene/protein annotation are vital for discovery verification.
- Previous studies identified Serine Threonine Kinase 19 (STK19) as a melanoma driver.
Purpose of the Study:
- To investigate the accuracy of STK19 gene and protein annotations in public databases.
- To emphasize the importance of rigorous data curation in cancer genomics.
Main Methods:
- Comparative analysis of STK19 gene and protein sequences.
- Verification against established biological data and literature.
- Assessment of annotation consistency across multiple bioinformatics databases.
Main Results:
- Identified inaccuracies in STK19 gene annotations within frequently used databases.
- Discovered incorrect protein annotations for STK19 in major bioinformatics resources.
- Highlighted discrepancies between database entries and known STK19 functions.
Conclusions:
- Existing STK19 annotations in public databases are unreliable.
- Manual curation and validation are essential to correct erroneous gene and protein data.
- Accurate annotation is critical for the reliable identification and study of cancer drivers.

8.8K
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.

6.2K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

03:03mTOR Signaling and Cancer Progression
4.2K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

01:12Loss of Tumor Suppressor Gene Functions
5.5K
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...
