Cadherin EGF LAG seven-pass G-type receptor 1 (CELSR1) is a member of the flamingo subfamily, part of the cadherin superfamily. The flamingo subfamily consists of nonclassic-type cadherins; a subpopulation that does not interact with catenins. The flamingo cadherins are located at the plasma membrane and have nine cadherin domains, seven epidermal growth factor-like repeats and two laminin A G-type repeats in their ectodomain. They also have seven transmembrane domains, a characteristic unique to this subfamily. It is postulated that these proteins are receptors involved in contact-mediated communication, with cadherin domains acting as homophilic binding regions and the EGF-like domains involved in cell adhesion and receptor-ligand interactions.CELSR1 is a developmentally regulated, neural-specific gene which plays an unspecified role in early embryogenesis [taken from NCBI Entrez Gene (Gene ID: 9620)].
