Recombinant Human PDE4A

• Cat.No.: PDE4A-29933TH
• Product Overview: Recombinant full length Human PDE4A, isoform 4 with N terminal proprietary tag. Predicted MW 97.24 kDa.

Specification

• Description: The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase (PDE) family, and PDE4 subfamily. This PDE hydrolyzes the second messenger, cAMP, which is a regulator and mediator of a number of cellular responses to extracellular signals. Thus, by regulating the cellular concentration of cAMP, this protein plays a key role in many important physiological processes. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

Q&As

How effective are PDE4A inhibitors in the treatment of asthma?

The inhibitors have been used in the treatment of asthma, and studies have shown that they can significantly reduce the number of asthma attacks and the use of drug D.

How to introduce the structure of PDE4A?

This protein has multiple conserved regions and different subtypes, which is of great significance for the selective inhibition of drugs.

What is a selective PDE4A inhibitor?

Selective PDE4A inhibitors refer to drug molecules that target only the PDE4A protein and do not inhibit other PDE4 homologs.

What is the mechanism by which PDE4A regulates T cell-mediated autoimmune responses?

It plays an important role in the activation and regulation of T cells by regulating cAMP levels, and is involved in T cell-mediated autoimmune responses.

Are levels of PDE4A associated with sleep disturbances?

Studies have shown that PDE4A depletion may be related to sleep-wake behavior and time stress response, but its specific role needs to be further studied.

What is the expression pattern of PDE4A in T cells?

In T cells, PDE4A is mainly expressed in the cytoplasm and peripheral regions of the nuclear membrane.
