About APBA1

Cytogenetic location: 9q21.12 Genomic coordinates (GRCh38): 9:69,427,532-69,673,013 (from NCBI)

This gene has 4 transcripts (splice variants), 1 gene allele, 271 orthologues and 4 paralogues. Broad expression in brain (RPKM 13.2), spleen (RPKM 2.4) and 17 other tissues.

Summary

The protein encoded by this gene is a member of the X11 protein family. It is a neuronal adapter protein that interacts with the Alzheimer's disease amyloid precursor protein (APP). It stabilizes APP and inhibits production of proteolytic APP fragments including the A beta peptide that is deposited in the brains of Alzheimer's disease patients. This gene product is believed to be involved in signal transduction processes. It is also regarded as a putative vesicular trafficking protein in the brain that can form a complex with the potential to couple synaptic vesicle exocytosis to neuronal cell adhesion.
