Phenomena and Processes

WD40 Repeats

Protein interaction motifs of approximately 40 amino acids that usually terminate in TRYPTOPHAN and ASPARTIC ACID. They form characteristic beta-propeller structures and occur in many eukaryotic proteins that function in a variety of cellular processes. Proteins that contain WD40 repeats often function as assembly platforms for MULTIPROTEIN COMPLEXES.

Abstract

Protein interaction motifs of approximately 40 amino acids that usually terminate in TRYPTOPHAN and ASPARTIC ACID. They form characteristic beta-propeller structures and occur in many eukaryotic proteins that function in a variety of cellular processes. Proteins that contain WD40 repeats often function as assembly platforms for MULTIPROTEIN COMPLEXES.
