Protein tandem repeats
Videos
An array of protein tandem repeats is defined as several adjacent copies having the same or similar sequence motifs. These periodic sequences are generated by internal duplications in both coding and

Armadillo repeat
Videos
An armadillo repeat is a characteristic, repetitive amino acid sequence of about 42 residues in length that is found in many proteins. Proteins that contain armadillo repeats typically contain several
Protein tandem repeats
…Common examples of protein tandem repeat structures: the WD40 repeat domain of beta-TrCP (green), leucine-rich repeat domain of TLR2 (red), armadillo repeat domain of beta-catenin (blue), ankyrin repeat domain of ANKRA2 (orange), kelch repeat domain of Keap1 (yellow) and HEAT repeat domain of a PP2A regulatory…
