Gene nomenclature and protein nomenclature are not separate endeavors; they are aspects of the same whole. Any name or symbol used for a protein can potentially also be used for the gene that encodes it, and vice versa.
At the top level are all alpha proteins (domains consisting of alpha helices), all beta proteins (domains consisting of beta sheets), and mixed alpha helix/beta sheet proteins. While most proteins adopt a single stable fold, a few proteins can rapidly interconvert between one or more folds. These are referred to as metamorphic proteins. [5]
STAT5 proteins are involved in cytosolic signalling and in mediating the expression of specific genes. [2] Aberrant STAT5 activity has been shown to be closely connected to a wide range of human cancers , [ 3 ] and silencing this aberrant activity is an area of active research in medicinal chemistry .
Pyruvate kinase, a protein with three domains (In molecular biology, a protein domain is a region of a protein's polypeptide chain that is self-stabilizing and that folds independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains, and a domain may appear in a variety of ...
The protein manufacturing cost remains high and there is a growing demand to develop cost efficient and rapid protein purification methods. Understanding the different protein purification methods and optimizing the downstream processing is critical to minimize production costs while maintaining the quality of acceptable standards of homogeneity.

It is currently most often used in the field of immunology and protein analysis, often used to separate different proteins or isoforms of the same protein into separate bands. These can be transferred onto a nitrocellulose or PVDF membrane to be probed with antibodies and corresponding markers, such as in a western blot .
homonym: names spelled identically, but, in some codes, names spelled similarly, as defined by the code senior homonym (zoology): the first legitimate use of the name which generally takes priority; junior homonym (zoology), later homonym (botany): a later and generally illegitimate use, though in some circumstances the later name is allowed to ...
Proteins of the erythrocyte membrane separated by SDS-PAGE according to their molecular masses. SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.
