The function of CDHR3 (cadherin related family member 3, Ensembl gene identifier ENSG00000128536) is as follows. Cadherins are calcium-dependent cell adhesion proteins. They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types. (Microbial infection) Acts as a receptor for human rhinovirus C. .
