Summaries for APBA1 Gene

Entrez Gene Summary for APBA1 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.

GeneCards Summary for APBA1 Gene

APBA1 (Amyloid Beta (A4) Precursor Protein-Binding, Family A, Member 1) is a Protein Coding gene. Diseases associated with APBA1 include neuronal intranuclear inclusion disease. GO annotations related to this gene include protein complex binding and phosphatidylinositol-4,5-bisphosphate binding. An important paralog of this gene is APBA2.

UniProtKB/Swiss-Prot for APBA1 Gene

  • Putative function in synaptic vesicle exocytosis by binding to Munc18-1, 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

    Quaternary structure:
    • Part of a multimeric complex containing Munc18-1 and syntaxin-1. Also part of the brain-specific heterotrimeric complex LIN-10/X11-alpha, LIN-2/CASK, and LIN7. Both isoform 1 and isoform 2 bind to the cytoplasmic domain of amyloid protein (APP). Interacts (via PDZ 1 and 2 domains) with FSPB. Isoform 2, but not isoform 1, interacts (via its truncated PID domain) with active, GTP-bound RAB6A and RAB6B.

  • Q02410
  • Composed of an N-terminal domain that binds Munc18-1 and LIN-2/CASK, a middle phosphotyrosine-binding domain (PID/PTB) that mediates binding with the cytoplasmic domain of the beta-amyloid precursor protein, and two C-terminal PDZ domains thought to attach proteins to the plasma membrane
  • The autoinhibitory helix linker occludes the APP binding site.
  • The PID domain, truncated by 11 amino acids, as observed in isoform 2, but not full-length, mediates the interaction with RAB6A and RAB6B.
  • Contains 2 PDZ (DHR) domains.
  • Contains 1 PID domain.
