Flamingo is a member of the adhesion-GPCR family of proteins. Flamingo has sequence homology to cadherins and G protein-coupled receptors (GPCR). Flamingo was originally identified as a Drosophila protein involved in planar cell polarity.[1] Mammals have three flamingo homologs, CELSR1, CELSR2, CELSR3. In mice, all three have distinct expression patterns in organs such as the kidney, skin, and lungs, as well as the brain.[2]
Flamingo is an atypical cadherin, with a cadherin-like extracellular domain, composed of cadherin and EGF adhesive repeats, that can bind to other Flamingo proteins expressed on neighboring cells. The transmembrane domain, however, is a 7-pass membrane domain most structurally similar to that of a G protein-coupled receptor, though it is not known to interact with G protein.[3]
