Summary: Enables actin binding activity and synaptic receptor adaptor activity. Involved in sensory perception of sound. Acts upstream of or within behavioral response to cocaine; calcium-mediated signaling; and regulation of G protein-coupled receptor signaling pathway. Located in apical part of cell; cytoplasm; and stereocilium tip. Is active in glutamatergic synapse and postsynaptic density. Is expressed in several structures, including central nervous system; cranial nerve; jaw; sensory organ; and tongue. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 68. Orthologous to human HOMER2 (homer scaffold protein 2). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
