9.A.14.6.2
CD97 antigen or adhesion GPCR (ADGRE5), of 835 aas amd 7 C-terminal TMSs. They play a role in tumorigenesis (Aust et al. 2016). Maser and Calvet 2020 reviewed structural and functional features shared by polycystin-1 (TC# 1.A.5.1.1) and the adhesion GPCRs and discussed the implications of such similarities for our understanding of the functions of this complicated protein.
