Pumilio repeats, also known as PUF repeats, form RNA-binding protein domains that recognize specific RNA sequences. These proteins regulate gene expression by influencing messenger RNA stability, translation, and other processes involved in cell development and function.
Disorder-to-order transitions allow intrinsically disordered protein regions to become structured during binding. Explore their mechanisms and roles in molecular recognition, signaling and regulation.
Molecular recognition features (MoRFs) are flexible protein regions that become structured when they bind partners. Learn how MoRFs regulate protein interactions, signaling and cellular functions.
Intrinsically disordered proteins (IDPs) and regions (IDRs) lack stable three-dimensional structures but play important roles in protein interactions, signaling, regulation, degradation and cellular organization.
Intrinsically disordered regions (IDRs) are flexible protein regions that regulate protein interactions, signaling, modification, degradation and biomolecular organization. Learn how IDRs function in cellular regulation.
Short linear motifs (SLiMs) are small sequence elements that regulate protein–protein interactions, signaling, localization and protein degradation. Learn how SLiMs work and why they are important in cellular regulation.
SH2, SH3 and PDZ domains are major protein–protein interaction domains. Learn how they recognize phosphotyrosine, proline-rich and C-terminal motifs to organize cellular signaling complexes.
Protein–protein interaction domains allow proteins to recognize and bind specific partners. Explore SH2, SH3 and PDZ domains, interaction motifs, coiled-coils, signaling and protein complex formation.
Quaternary structure describes how multiple protein subunits assemble into functional complexes. Explore dimers, heterodimers, oligomers, protein interfaces, cooperativity and molecular machines.
Protein aggregation and functional oligomerization both involve protein–protein association but differ in organization, regulation and biological consequences. Compare their key features in this detailed table.
Protein oligomerization can produce functional molecular complexes, while abnormal protein assembly can lead to aggregation. Learn the mechanisms, differences and biological significance of both processes.
Homodimers contain two copies of the same protein, while heterodimers contain two different protein subunits. Learn how both types of dimers regulate protein structure and function.
Homodimers contain two copies of the same protein, while heterodimers contain two different protein subunits. Learn how both types of dimers regulate protein structure and function.
Protein oligomerization is the assembly of multiple protein molecules into functional complexes. Explore homo- and hetero-oligomers, molecular interfaces, protein stability, signaling, enzymes and cellular organization.
Protein dimerization is the association of two protein molecules to form a functional dimer. Explore homodimers, heterodimers, interaction interfaces, coiled-coils and roles in cellular regulation.
