蛋白结构(Molecular Characterization)

PDE4A Structure

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 47.1 kDa. The protein migrates as 45-52 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制剂(Formulation)

Supplied as 0.2 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with glycerol as protectant.

Report

 

活性(Bioactivity)

Measured by its ability to convert cAMP to 5'AMP. The specific activity is >140,000 pmol/min/μg (QC tested).

Protocol

 

背景(Background)

cAMP-specific 3',5'-cyclic phosphodiesterase 4A (PDE4A) is an enzyme that in humans is encoded by the PDE4A gene. It belongs to the PDE family who hydrolyze 3′-5′-cyclic adenosine monophosphate (cyclic AMP) to 5′-adenosine monophosphate (AMP). PDE enzyme family plays a pivotal role in regulating levels of the second messenger cAMP. Consequently, PDE4 inhibitors have been investigated as a therapeutic strategy to enhance cAMP signaling in a broad range of diseases, including several types of cancers, as well as in various neurologic, dermatological, and inflammatory diseases.
