What is the official name of the SNCAIP gene?
The official name of this gene is “synuclein, alpha interacting protein.”
SNCAIP is the gene's official symbol. The SNCAIP gene is also known by other names, listed below.
What is the normal function of the SNCAIP gene?
The SNCAIP gene provides instructions for making a protein called synphilin-1 and a slightly different version of this protein called synphilin-1A. These proteins are produced in the brain. They are usually located in specialized structures called presynaptic terminals, found at the tips of nerve cells. In nerve cells, synphilin-1 and synphilin-1A interact with another protein called alpha-synuclein. The functions of synphilin-1 and synphilin-1A, however, are unknown.
Does the SNCAIP gene share characteristics with other genes?
The SNCAIP gene belongs to a family of genes called ANKRD (ankyrin repeat domain containing).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? (http://ghr.nlm.nih.gov/handbook/howgeneswork/genefamilies) in the Handbook.
Where is the SNCAIP gene located?
Cytogenetic Location: 5q23.2
Molecular Location on chromosome 5: base pairs 121,647,454 to 121,799,793
The SNCAIP gene is located on the long (q) arm of chromosome 5 at position 23.2.
More precisely, the SNCAIP gene is located from base pair 121,647,454 to base pair 121,799,793 on chromosome 5.
