Specialized Peptide Structures and Functions

The term "sigma peptide" can also denote specific molecular entities with defined roles.6qzs - 14-3-3 sigma in complex with FOXO1 pS256 peptide For instance, the "intracellular sigma peptide" is a membrane-permeable mimetic of protein tyrosine phosphatase sigma (PTPσ), which plays a role in neural receptor binding. Another definition describes a "sigma peptide" as one where an end is bonded within the chain, often via a disulfide group, leaving only one end free. This structural characteristic can influence a peptide's stability and function. In broader biological contexts, sigma factors, such as the stress-responsive alternative sigma factor SigB, control a significant number of genes involved in stress response in certain organisms, demonstrating a different application of the 'sigma' prefix in biological nomenclature.作者：P Bouchard·1993·被引用次数：54—Recently, it was proposed thatneuropeptide Y (NPY) and peptide YY (PYY) could act as endogenous ligands for sigma binding sites, ...
