Clan: MtN3-like (CL0141)

Summary

MtN3-like, vesicle-trafficking cargo-receptors Add an annotation

The clan forms a large and diverse family of proteins with seven transmembrane helices, common topology and, most likely, similar function. Their coding genes exist in all eukaryota and in several prokaryota. Some are responsible for metabolic diseases (cystinosis, congenital disorder of glycosylation), others are candidate genes for genetic disorders (cleft lip and palate, certain forms of cancer) or solute uptake and efflux (SWEETs) and many have not yet been assigned a function. Comparison with the properties of well-annotated clan members suggests that the proteins could be involved in protein trafficking and serve as cargo receptors in vesicle trafficking [3].

This clan contains 5 families and the total number of domains in the clan is 7738. The clan was built by J Mistry.
