Leucine Rich Repeat Containing Protein 59 (LRRC59)

LRRC59 Contains 5 LRR (leucine-rich) repeats. A leucine-rich repeat (LRR) is a protein structural motif that forms an α/β horseshoe fold. It is composed of repeating 20–30 amino acid stretches that are unusually rich in the hydrophobic amino acid leucine. Typically, each repeat unit has beta strand-turn-alpha helix structure, and the assembled domain, composed of many such repeats, has a horseshoe shape with an interior parallel beta sheet and an exterior array of helices. One face of the beta sheet and one side of the helix array are exposed to solvent and are therefore dominated by hydrophilic residues. The region between the helices and sheets is the protein"""s hydrophobic core and is tightly sterically packed with leucine residues.Leucine-rich repeats are frequently involved in the formation of protein–protein interactions.
