IMPA2, or Inositol monophosphatase 2, demonstrates enzymatic activity by utilizing various substrates such as myo-inositol monophosphates, scylloinositol 1,4-diphosphate, glucose-1-phosphate, beta-glycerophosphate, and 2'-AMP. Additionally, it has been implicated as the pharmacological target for the action of lithium ions (Li⁺) in the brain. IMPA2 Protein, Human (His) is the recombinant human-derived IMPA2 protein, expressed by E. coli , with N-6*His labeled tag.
