The exact function of KIAA0644 is not known. It is, however, a member of the leucine-rich repeat family of proteins, which are known to be involved in protein-protein interactions. This protein is known to interact with the TLR4 protein.
TRIL is a component of the TLR4 complex and is induced in a number of cell types by lipopolysaccharide (LPS).[2]
Protein sequence
The main isoform of the human protein is 811 amino long and is composed primarily of leucine (17%), alanine and arginine (~10%), and glycine (~ 8.5%) residues. The protein sequence is predicted to consists mostly of α-helices and a few β-sheet
Homology
KIAA0644 is conserved well among mammals but can be found in all chordates with lower sequence identities.
Gene neighborhood
The KIAA0644 gene is neighbors to mRNA-cAMP responsive element binding gene downstream and mRNA carboxypeptidase and serine carboxypeptidase gene upstream [3][4]
