Leucine Rich Repeat Containing Protein 40 (LRRC40)

LRRC40 is a 602 amino acid protein with a molecular weight of 68.254 kDa and an isoelectric point of 6.04. LRRC40 is expected to localize to the nucleusand has no transmembrane domains to anchor it to the nuclear membrane. LRRC40 has many predicted phosphorylation sites. Of the 19 predicted phosphoserine sites, only two are conserved within the orthologs. The secondary structure of the protein has a pattern within the leucine repeat regions. Each leucine repeat has a β-sheet and α-helix. The image to the right shows the particular horseshoe-like structure of a protein with many leucine rich repeats. Depending on the area where the LRRs are located, other proteins can bind within the curve of the horseshoe or attach to the outside of the protein.
