Modes of allosteric regulation of the ubiquitination machinery [PDF]
Current Opinion in Structural Biology, 2020 Ubiquitination is a post-translational modification crucial for cellular signaling. A diverse range of enzymes constitute the machinery that mediates attachment of ubiquitin onto target proteins. This diversity allows the targeting of various proteins in a highly regulated fashion.

Allosteric modulation of G protein-coupled receptor signaling
Frontiers in Endocrinology, 2023 G protein-coupled receptors (GPCRs), the largest family of transmembrane proteins, regulate a wide array of physiological processes in response to extracellular signals. Although these receptors have proven to be the most successful class of drug targets,

Allosteric regulation of Argonaute proteins by miRNAs [PDF]
Nature Structural & Molecular Biology, 2010 Small interfering RNAs (siRNAs) and microRNAs (miRNAs) bind to Argonaute (AGO) family proteins to form a related set of effector complexes that have diverse roles in post-transcriptional gene regulation throughout the eukaryotic lineage. Here sequence and structural analysis of the MID domain of the AGO proteins identified similarities with a family of

Allosteric regulation of phenylalanine hydroxylase [PDF]
Archives of Biochemistry and Biophysics, 2012 The liver enzyme phenylalanine hydroxylase is responsible for conversion of excess phenylalanine in the diet to tyrosine. Phenylalanine hydroxylase is activated by phenylalanine; this activation is inhibited by the physiological reducing substrate tetrahydrobiopterin.
