Schematic representation of structural classes of protein according to the CATH classification scheme. [1] Proteins are a class of macromolecular organic compounds that are essential to life. They consist of a long polypeptide chain that usually adopts a single stable three-dimensional structure.
Regarding the first duality (same symbol and name for gene or protein), the context usually makes the sense clear to scientific readers, and the nomenclatural systems also provide for some specificity by using italic for a symbol when the gene is meant and plain (roman) for when the protein is meant.
However it is appropriate to list the names of those who made key discoveries concerning the gene or protein in this section (e.g., the scientist or group that originally cloned the gene, determined its function, linked it to a disease, won a major award for the discovery, etc.).
Protein identification is the process of assigning a name to a protein of interest (POI), based on its amino-acid sequence. Typically, only part of the protein’s sequence needs to be determined experimentally in order to identify the protein with reference to databases of protein sequences deduced from the DNA sequences of their genes.
A medicinal compound made from living organisms, such as a serum or a vaccine, could be characterized as biological data. Biological data is highly complex when compared with other forms of data. There are many forms of biological data, including text, sequence data, protein structure, genomic data and amino acids, and links among others.
The Protein Information Resource (PIR), located at Georgetown University Medical Center, is an integrated public bioinformatics resource to support genomic and proteomic research, and scientific studies.
The dbSNP accepts apparently neutral polymorphisms, polymorphisms corresponding to known phenotypes, and regions of no variation. It was created in September 1998 to supplement GenBank, NCBI’s collection of publicly available nucleic acid and protein sequences. [2] In 2017, NCBI stopped support for all non-human organisms in dbSNP. [3]
Protein purification is a critical process in molecular biology and biochemistry, aimed at isolating a specific protein from a complex mixture, such as cell lysates or tissue extracts. [9] The goal is to obtain the protein in a pure form that retains its biological activity for further study, including functional assays, structural analysis, or ...
