Introduction
The ankyrin repeat domain is a structural motif in proteins, consisting of 33 amino acids forming two alpha helices separated by loops . These domains are among the most common protein-protein interaction platforms in nature and are found in a wide variety of proteins across eukaryotes, bacteria, and archaea . Ankyrin repeat domains typically fold into a linear solenoid structure and are involved in diverse functions such as transcriptional regulation, cell cycle control, and signal transduction .
Key Biological Properties: Ankyrin repeat domains are characterized by their ability to mediate protein-protein interactions. They are highly conserved and can be found in proteins with various functions .
Expression Patterns and Tissue Distribution: Ankyrin repeat-containing proteins are ubiquitously expressed in many tissues. For instance, in plants, they play crucial roles in defense responses and development . In humans, they are involved in processes such as cytoskeletal integrity and ion transport .
