Summary
Predicted to be involved in cell adhesion. Predicted to act upstream of or within locomotory exploration behavior. Is active in postsynaptic membrane and presynaptic membrane. Orthologous to human LSAMP (limbic system associated membrane protein). [provided by Alliance of Genome Resources, Jul 2025]

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.
