protein_function: May play a role in craniofacial and inner earmorphogenesis during embryonic development. May act within theotic vesicle epithelium to control formation of the lateralsemicircular canal in the inner ear, possibly by restricting theexpression of NTN1 (By similarity)..
LRIG3 is a 1,119-amino acid protein that contains a signal peptide. This gene is mapped to chromosome 12q13.2. Northern blot analysis detected a 5.1-kb LRIG3 transcript in all tissues analyzed. Quantitative RT-PCR detected highest expression in stomach and lowest expression in blood. And quantitative RT-PCR of mouse tissues revealed ubiquitous expression, but the pattern of expression differed from that in human tissues. LRIG3 may play a role in craniofacial and inner ear morphogenesis during embryonic development. In addition, it may act within the otic vesicle epithelium to control formation of the lateral semicircular canal in the inner ear, possibly by restricting the expression of NTN1.
