Scope Note
Homer proteins belong to a family of adaptor and scaffold proteins which include Homer1, Homer2 and Homer3. Homer1 and Homer2 play a role in the regulation of calcium homeostasis, whereas Homer3 functions in stimulating changes in actin dynamics in neurons and T-cells. Homer proteins are best known as scaffold proteins at the post-synaptic density where they facilitate synaptic signaling. They function as a molecular switch in metabotropic glutamate receptor (MGluR) signaling, and are associated with human Fragile X syndrome.
