    Summary
    Acts upstream of or within several processes, including learning; neuromuscular process controlling balance; and regulation of store-operated calcium entry. Located in dendritic shaft and smooth endoplasmic reticulum. Is expressed in ganglia; hindlimb mesenchyme; nervous system; and retina. Orthologous to human JPH4 (junctophilin 4).

    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.
