Homer protein homolog 2 is a protein that in humans is encoded by the HOMER2 gene.^[3]^[4]^[5]

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. Four transcript variants encoding distinct isoforms have been identified for this gene.^[5]

Interactions

HOMER2 has been shown to interact with RYR1.^[6]
