PDE9A Active Protein

Description: Full-length recombinant human PDE9A was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag.
Scientific Background: PDE9A is a member of the phosphodiesterase (PDE) family that catalyzes the hydrolysis of cGMP to the monophosphate and thus plays an important role in signal transduction by regulating the intracellular concentration of cyclic nucleotides (1). Multiple transcript variants encoding several different isoforms have been found for PDE9A (2). These mRNAs differ in the use of specific combinations of exons located at the 5' end of the gene while the 3' half, encoding the catalytic domain of the protein, always has the same combination of exons. PDE9A has been used in the study of gene- disease association, gene-environment interaction, and pharmacogenomic/toxicogenomic. PDE9A is mainly expressed in spleen, small intestine, and brain.

Small volumes of PDE9A active protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
