Anti-leucine-rich repeats and immunoglobulin like domains 3 antibodies enable researchers to detect and measure the leucine-rich repeats and immunoglobulin like domains 3 antigen in biological samples. This target is a reported synonym of the LRIG3 gene, which encodes leucine rich repeats and immunoglobulin like domains 3. This protein is believed to play a role in craniofacial and inner ear morphogenesis during embryonic development. The human version of leucine-rich repeats and immunoglobulin like domains 3 has a canonical amino acid length of 1119 residues and a protein mass of 123.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasmic vesicles and cell membrane of cells and widely expressed in many tissue types.
