Gene Gene information from NCBI Gene database.
Entrez ID 83464
Gene name Aph-1B gamma-secretase subunit
Gene symbol APH1B
Synonyms (NCBI Gene)
APH-1BPRO1328PSFLTAAV688aph-1beta
Chromosome 15
Chromosome location 15q22.2
Summary This gene encodes a multi-pass transmembrane protein that is a functional component of the gamma-secretase complex, which also contains presenilin and nicastrin. This protein represents a stabilizing cofactor for the presenilin holoprotein in the complex.
