GDA is an enzyme responsible for the hydrolytic deamination of guanine. Studies in rat ortholog suggest this gene plays a role in microtubule assembly. Multiple transcript variants encoding different isoforms have been found for this gene. Source: Recombinant protein corresponding to aa1-454 from human GDA, fused to His-Tag at N-terminal, expressed in E. coli.
