APBA1

amyloid beta precursor protein binding family A member 1

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.

AD Risk Scores

About AD Risk Scores

The TREAT-AD Center at Emory-Sage-SGC has developed a Target Risk Score (TRS) to objectively rank the potential involvement of specific genes in AD. The TRS is derived by summing two component risk scores, the Genetic Risk Score and the Multi-omic Risk Score, each of which is derived from a meta-analysis of multiple harmonized data sets. More information about the methodology used to define these risk scores is available here.

AD Risk Scores for APBA1

The TRS for APBA1, along with the component Genetic and Multi-omic Risk Scores, is shown here. The scores for APBA1 are superimposed on the genome-wide score distributions. If No Data is Currently Available is displayed for a score, that score was not calculated for APBA1.

Biological Domain Classification

About Biological Domains

A biological domain represents a standardized area of biology defined by a set of discrete, biologically coherent GO terms. The TREAT-AD Center at Emory-Sage-SGC has defined nineteen biological domains associated with AD, and objectively mapped genes to those biological domains using GO term annotations. More information about the methodology used to define AD biological domains, and to generate genome-wide biological domain mappings, is available here.

Biological Domains for APBA1

Select a biological domain on the left to see the list of GO terms that link APBA1 to it on the right. The percentage value displayed next to the currently selected biological domain indicates the proportion of APBA1's total unique GO terms that map to the biological domain. The ratio displayed on the right indicates how many of the biological domain's total GO terms APBA1 is annotated with.
