Summary
The protein encoded by this gene is a beta-amyloid peptide-binding protein. It contains a structural module related to that of the seven transmembrane domain G protein-coupled receptor superfamily and known to be important in heterotrimeric G protein activation. Beta-amyloid peptide has been established to be a causative factor in neuron death and the consequent diminution of cognitive abilities observed in Alzheimer's disease. This protein may be a target of neurotoxic beta-amyloid peptide, and may mediate cellular vulnerability to beta-amyloid peptide toxicity through a G protein-regulated program of cell death. Several transcript variants have been found for this gene. [provided by RefSeq, Feb 2016]

GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. A two-electrode voltage-clamp technique is used to determine that BBP is not directly coupled to G alpha(i/o), G alpha(s), or G alpha(q) proteins and that BBP may need a component other than amyloid precursor protein to exert its toxic effect with A beta.

  2. sAPP increased the proportion of migrating keratinocytes and their directional persistence. sAPP appeared to operate synergistically with fibronectin with respect to its motogenic effect.
    Title: The secretory beta-amyloid precursor protein is a motogen for human epidermal keratinocytes.
  3. These findings reveal that low density lipoprotein receptor-related protein 1B is a novel binding partner of beta-amyloid precursor protein (APP) that functions to decrease APP processing to amyloid beta peptides.

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.
