The field of de novo design is examined in the light of current theories of protein folding. The most carefully characterized designed proteins show many of the characteristics of molten globules or protein folding intermediates. Thus, it is unclear whether or not the objective of designing ...
de novo designpeptideNumber of naturally occurring primary sequences of proteins is an infinitesimally small subset of the possible number of primary sequences that can be synthesized using 20 amino acids. Prevailing views ascribe this to slow and incremental mutational/selection evolutionary mechanisms....
This last variable could be just about anything; there are proteins that bind to other proteins (like antibodies), cut other proteins (proteases), or bind DNA (transcription factors). Roughly a dozen sequence-to-function datasets already exist (see Supplemental Table 1 in this 2022 study), ...
Named after the Red Queen in Lewis Carroll'sAlice Through the Looking Glasswho is continually running to stay in the same place. This describes an evolutionary scenario in which two interacting loci (often one from a parasite and one from a host) are both rapidly evolving but the relationship...
The caveat with all such generalizations is that it is not (cannot be) defined which sort of proteins they are referring to. Using the word as is, implies that we are at full confidence of its meaning and coverage, i.e. that (i) we have discovered all (sort of) proteins, and (ii...

What makes them different is which genes are transcribed and translated into proteins (different proteomes)—accounting for differences in structure and function in the different types of cells within an organism. Because each type of specialized cell will have a different pattern of gene expression ...
A major advance in our understanding of how cannabis works has been the discovery of specific receptor proteins in the brain that recognize cannabinoids including THC. Among several that have been identified, the two primary types of cannabinoid receptors are CB1 and CB2, both coupled to G-protein...

GLUT transporters are primarily made up of 13 multiple homologous proteins (GLUT 1–12 and 14) and they are located throughout the body often exhibiting tissue specificities[36]. The capacity for fructose absorption in humans is not completely clear, but early studies suggested that fructose ...
