PDE4D Antibody – Rabbit

This gene encodes one of four mammalian counterparts to the fruit fly 'dunce' gene. The encoded protein has 3',5'-cyclic-AMP phosphodiesterase activity and degrades cAMP, which acts as a signal transduction molecule in multiple cell types. This gene uses different promoters to generate multiple alternatively spliced transcript variants that encode functional proteins.[provided by RefSeq, Sep 2009]

PDE4D: Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes. Homodimer for the long isoforms. Isoforms with truncated N-termini are monomeric. Isoform 3 is part of a ternary complex containing PRKAR2A, PRKAR2B and AKAP9. Interacts with PDE4DIP. Identified in a complex composed of RYR1, PDE4D, PKA, FKBP1A and protein phosphatase 1 (PP1). Isoform 5, isoform N3 and isoform 12 bind GNB2L1 via their unique N-terminus. Binds ARRB2. Widespread; most abundant in skeletal muscle. Isoform 6 is detected in brain. Isoform 8 is detected in brain, placenta, lung and kidney. Isoform 7 is detected in heart and skeletal muscle. Inhibited by rolipram. Activated by phosphatidic acid. Belongs to the cyclic nucleotide phosphodiesterase family. PDE4 subfamily. 12 isoforms of the human protein are produced by alternative splicing.
