PDE4D Antibody – Rabbit Polyclonal

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.
