    See all PDE4A primary antibodies
  • Description
    Rabbit polyclonal to PDE4A (phospho S)
  • SpecificityThis antibody detects all known long-from variants of PDE4A, including PDE4A4, PDE4A5, PDE4A8, PDE4Ax when phosphorylated at the PKA phophorylation site. It will not cross-react with PDE4A phosphorylated at the ERK phosphorylation site. It does not cross-react with PDE4B, PDE4D or any other member of the PDE family.
  • Tested applicationsSuitable for: WB, IPmore details

Application Abreviews Notes
WB 1/2500. Detects a band of approximately 71 kDa (predicted molecular weight: 66 kDa). Detects bands at 66 kDa (PDE4A1), 109 kDa (PDE4A5), 106 kDa(PDE4A8), 102 kDa (PDE4Ax) and 76 kDa (testis specific PDE4A variant).
IP Use at an assay dependent dilution.


  • FunctionHydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes.
  • Tissue specificityIsoform 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 (at protein level).
  • PathwayPurine metabolism; 3',5'-cyclic AMP degradation; AMP from 3',5'-cyclic AMP: step 1/1.
  • Sequence similaritiesBelongs to the cyclic nucleotide phosphodiesterase family. PDE4 subfamily.
  • Post-translational
    Phosphorylated at Ser-686 and Ser-688 when expressed in S.frugiperda cells. Isoform 2 and isoform 7 are activated by phosphorylation at Ser-119 and Ser-123 respectively by PKA.
    Proteolytically cleaved by caspase-3.
  • Cellular localizationCytoplasm > perinuclear region; Cytoplasm > perinuclear region. Cell projection > ruffle membrane; Cytoplasm. Membrane. Predominantly cytoplasmic and Membrane. Isoform 4 has propensity for association with membranes.
