Rabbit anti-Human PDE4A Polyclonal Antibody | anti-PDE4A antibody
PDE4A Antibody - N-terminal region
NCBI and Uniprot Product Information
NCBI 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.[provided by RefSeq, Jul 2011]
Uniprot Description
PDE4A: Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes. Isoform 1 interacts with LYN. Isoform 2 and isoform 6 interact weakly with LYN. Isoform 1, isoform 2 and isoform 6 interact with ARRB2. Isoform 1 is widely expressed. Isoform 2 is abundant in liver, stomach, testis, thyroid and adrenal glands. It is also found in placenta, kidney, pancreas, ovary, uterus, skin, monocytes, mast cells, macrophages, as well as in bronchial smooth muscle. Isoform 6 is expressed at high levels in the heart and small intestine. It is also found in the brain, kidney, spleen, colon, salivary gland, ovary and peripheral blood lymphocytes. Isoform 7 is expressed predominantly in skeletal muscle and brain and at lower levels in the testis. Isoform 7 is expressed in the brain. Found in specific neuronal subpopulations in cortex, spinal cord and cerebellum. Isoform 1, isoform 2, isoform 6 and isoform 7 are inhibited by rolipram and cilomilast. Isoform 1, isoform 2 and isoform 6 are inhibited by 4-[(3-butoxy-4-methoxyphenyl)-methyl]- 2-imidazolidinone (Ro 20-1724), roflumilast and denbufylline. Belongs to the cyclic nucleotide phosphodiesterase family. PDE4 subfamily. 7 isoforms of the human protein are produced by alternative splicing.
