TLDRThe webinar, hosted by Peter Cooper and presented by Rana Morris, delves into the complexities of gene, protein, and chemical nomenclature. It highlights how evolving scientific understanding can lead to multiple names for the same entities, causing confusion in research and literature. The NCBI (National Center for Biotechnology Information) addresses this through its RefSeq project, which curates gene and protein names, and the PubChem project, which does the same for chemical compounds. The presentation outlines how to access and utilize the vast databases of names and synonyms through NCBI's Gene database and PubChem, including how to download bulk information via FTP. It also mentions the regular updates to these databases and directs users to the NCBI Insights Blog and YouTube channel for further guidance and resources.

πŸŽ“ Introduction to Gene, Protein, and Chemical Nomenclature

The first paragraph introduces the topic of the webinar, which is about the complexities of gene, protein, and chemical names, including aliases and synonyms. Peter Cooper welcomes the audience and introduces Rana Morris, who will present on the subject. The webinar aims to address the confusion that arises from the evolution of scientific nomenclature over time. Rana explains that the National Center for Biotechnology Information (NCBI) will share how they handle nomenclature issues internally and provide resources to help others navigate these complexities. The paragraph also highlights the importance of standardized naming for scientific communication and literature search.

🧬 Gene and Protein Nomenclature Management at NCBI

The second paragraph delves into how NCBI manages gene and protein nomenclature through the RefSeq group. It discusses the process of curating a list of terms for each gene or protein, including official symbols and names, as well as aliases from various reputable databases and expert submissions. The RefSeq group compiles this information and displays it on the Gene database, with gene symbols and protein names listed in their respective sections. The paragraph also provides an example of how this information is presented on the CDKN1A gene page, including the official gene symbol and protein name as designated by the Human Gene Nomenclature Committee (HGNC).

NCBI is a vital resource in the field of bioinformatics, providing databases and tools for scientific research. In the video, NCBI is highlighted for its role in standardizing and providing access to information on gene symbols, protein names, and chemical compound synonyms through platforms like the Gene database and PubChem.
πŸ’‘RefSeq
RefSeq, or the Reference Sequence project, is a group within NCBI that curates a comprehensive list of terms used for genes and proteins. The video mentions how RefSeq compiles official gene symbols, protein names, and aliases from various sources, including literature and databases, to help researchers navigate the complexities of nomenclature.
πŸ’‘IUPAC Name
The IUPAC name, or International Union of Pure and Applied Chemistry name, is the official and systematic nomenclature for chemical compounds based on their atomic structure. The video discusses how IUPAC names are used alongside other identifiers to ensure precise chemical identification, despite the existence of marketable names like Tamoxifen.
πŸ’‘Aliases or Synonyms
Aliases or synonyms are alternative names for genes, proteins, or chemical compounds. The video emphasizes the importance of recognizing these alternative terms to avoid confusion and ensure accurate scientific communication. NCBI databases, such as Gene and PubChem, include these synonyms to facilitate comprehensive searches.
πŸ’‘FTP Site
