GADL1 (Glutamate Decarboxylase Like 1) is a protein related to glutamate decarboxylases, enzymes involved in the production of the neurotransmitter GABA. Although its precise function is not completely understood, GADL1 is believed to play a role in amino acid metabolism and neurotransmitter synthesis. It is being studied for its potential involvement in neurological functions and associated disorders.
