Summary
Predicted to enable amyloid-beta binding activity and molecular adaptor activity. Predicted to be involved in several processes, including maintenance of lens transparency; negative regulation of cell cycle phase transition; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within extracellular matrix organization; generation of neurons; and regulation of apoptotic process. Predicted to be located in Golgi apparatus; early endosome; and endoplasmic reticulum. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in Alzheimer's disease and cognitive disorder. Orthologous to human APBB2 (amyloid beta precursor protein binding family B member 2).

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.
