Also known as: Vesl-2
Summary: Enables G protein-coupled glutamate receptor binding activity; identical protein binding activity; and protein domain specific binding activity. Predicted to be involved in several processes, including G protein-coupled glutamate receptor signaling pathway; negative regulation of calcineurin-NFAT signaling cascade; and negative regulation of interleukin-2 production. Predicted to act upstream of or within behavioral response to cocaine; calcium-mediated signaling; and regulation of G protein-coupled receptor signaling pathway. Located in dendrite; neuronal cell body; and plasma membrane. 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]
Expression: Biased expression in Muscle (RPKM 97.7), Heart (RPKM 88.2) and 9 other tissues See more

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.
