    Summary
    Involved in regulation of postsynaptic density assembly; regulation of presynapse assembly; and synaptic membrane adhesion. Located in cell surface. Is active in GABA-ergic synapse and glutamatergic synapse. Is expressed in several structures, including central nervous system; liver; primary head vein; reproductive system; and sensory organ. Orthologous to human LRFN4 (leucine rich repeat and fibronectin type III domain containing 4). [provided by Alliance of Genome Resources, Oct 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.
