Homer protein homolog 3 is a protein that in humans is encoded by the HOMER3 gene.

Function

This gene encodes a member of the homer family of dendritic proteins. Members of this family regulate group 1 metabotrophic glutamate receptor function. The encoded protein may be involved in cell growth.

Interactions

HOMER3 has been shown to interact with TRPC1 and RYR1.
