About APBA2

Cytogenetic location: 15q13.1 Genomic coordinates (GRCh38): 15:28,885,974-29,118,315 (from NCBI)

This gene has 13 transcripts (splice variants), 1 gene allele, 267 orthologues and 4 paralogues. Biased expression in brain (RPKM 16.8), spleen (RPKM 2.5) and 4 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.
