Recombinant Human Leucine-rich repeat flightless-interacting protein 2 (LRRFIP2)

Uniprot Id

Q9Y608

Target Species

Human

Target Name

LRRFIP2

Target Full Name

Leucine-rich repeat flightless-interacting protein 2

Target Function

May function as activator of the canonical Wnt signaling pathway, in association with DVL3, upstream of CTNNB1/beta-catenin. Positively regulates Toll-like receptor (TLR) signaling in response to agonist probably by competing with the negative FLII regulator for MYD88-binding.

Target Protein Families

LRRFIP family

Target Tissue Specificity

Widely expressed, with highest levels in heart and skeletal muscle.

Target Background

The protein encoded by this gene, along with MYD88, binds to the cytosolic tail of toll-like receptor 4 (TLR4), which results in activation of nuclear factor kappa B signaling. The ubiquitin-like protein FAT10 prevents the interaction of the encoded protein and TLR4, thereby inactivating the nuclear factor kappa B signaling pathway. In addition, this protein can downregulate the NLRP3 inflammasome by recruiting the caspase-1 inhibitor Flightless-I to the inflammasome complex.
