Diversity and structural‐functional insights of alpha‐solenoid proteins

Protein Science, Volume 33, Issue 11, November 2024.
Abstract Alpha‐solenoids are a significant and diverse subset of structured tandem repeat proteins (STRPs) that are important in various domains of life. This review examines their structural and functional diversity and highlights their role in critical cellular processes such as signaling, apoptosis, and transcriptional regulation.
