Gene Gene information from NCBI Gene database.
Entrez ID 2760
Gene name Ganglioside GM2 activator
Gene symbol GM2A
Synonyms (NCBI Gene)
GM2-APGM2APSAP-3
Chromosome 5
Chromosome location 5q33.1
Summary This gene encodes a small glycolipid transport protein which acts as a substrate specific co-factor for the lysosomal enzyme beta-hexosaminidase A. Beta-hexosaminidase A, together with GM2 ganglioside activator, catalyzes the degradation of the gangliosid
