Summary: Predicted to enable signaling receptor activator activity and signaling receptor binding activity. Acts upstream of or within several processes, including convergent extension; regulation of non-motile cilium assembly; and vasculature development. Predicted to be located in Golgi-associated vesicle and membrane. Predicted to be active in several cellular components, including Golgi apparatus; early endosome; and membrane raft. Is expressed in several structures, including axis; nervous system; pleuroperitoneal region; segmental plate; and solid lens vesicle. Human ortholog(s) of this gene implicated in APP-related cerebral amyloid angiopathy; Alzheimer's disease (multiple); cognitive disorder; traumatic brain injury; and visual epilepsy. Orthologous to human APP (amyloid beta precursor protein). [provided by Alliance of Genome Resources, Nov 2024]

Data show that knock down of APP in zebrafish results in fish with reduced body length and a short, curly tail, and that wild-type human APP rescues the morphant phenotype, but the Swedish mutant APP, which causes familial AD (fAD), does not.

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.
