Summary: Predicted to enable identical protein binding activity and serine-type endopeptidase inhibitor activity. Predicted to be involved in axonogenesis and central nervous system development. Predicted to act upstream of or within several processes, including brain development; regulation of epidermal growth factor-activated receptor activity; and suckling behavior. Predicted to be located in nucleus. Predicted to be active in spine apparatus. Used to study Alzheimer's disease. Biomarker of neurodegenerative disease. Orthologous to human APLP2 (amyloid beta precursor like protein 2). [provided by Alliance of Genome Resources, Dec 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.
