Summaries for APBA2 Gene

Entrez Gene Summary for APBA2 Gene

  • 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. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for APBA2 Gene

APBA2 (Amyloid Beta Precursor Protein Binding Family A Member 2) is a Protein Coding gene. Diseases associated with APBA2 include Alzheimer Disease and Rectal Neoplasm. Among its related pathways are Protein-protein interactions at synapses and Transmission across Chemical Synapses. GO annotations related to this gene include beta-amyloid binding. An important paralog of this gene is APBA1.

UniProtKB/Swiss-Prot for APBA2 Gene

  • Putative function in synaptic vesicle exocytosis by binding to STXBP1, an essential component of the synaptic vesicle exocytotic machinery. May modulate processing of the beta-amyloid precursor protein (APP) and hence formation of beta-APP.
