General annotation (Comments)

Function	Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes.
Catalytic activity	Adenosine 3',5'-cyclic phosphate + H2O = adenosine 5'-phosphate.
Cofactor	Binds 2 divalent metal cations per subunit. Site 1 may preferentially bind zinc ions, while site 2 has a preference for magnesium and/or manganese ions.
Enzyme regulation	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. Ref.5 Ref.6 Ref.7
Pathway	Purine metabolism; 3',5'-cyclic AMP degradation; AMP from 3',5'-cyclic AMP: step 1/1.
Subunit structure	Isoform 1 interacts with LYN. Isoform 2 and isoform 6 interact weakly with LYN. Isoform 1, isoform 2 and isoform 6 interact with ARRB2. Ref.5 Ref.6
Subcellular location	Isoform 1: Cytoplasm › perinuclear region Ref.5 Ref.6 Ref.7. Isoform 2: Cytoplasm › perinuclear region. Cell projection › ruffle membrane Ref.5 Ref.6 Ref.7. Isoform 4: Membrane; Peripheral membrane protein. Note: Isoform 4 has propensity for association with membranes. Ref.5 Ref.6 Ref.7 Isoform 6: Cytoplasm › perinuclear region Ref.5 Ref.6 Ref.7. Isoform 7: Cytoplasm. Membrane. Note: Predominantly cytoplasmic. Ref.5 Ref.6 Ref.7
Tissue specificity	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 (at protein level). Ref.5 Ref.6 Ref.7
Post-translational modification	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. Ref.6 Ref.7 Ref.13 Ref.15 Proteolytically cleaved by caspase-3. Ref.6
Sequence similarities	Belongs to the cyclic nucleotide phosphodiesterase family. PDE4 subfamily.
Biophysicochemical properties	Kinetic parameters: KM=4.0 µM for cAMP (isoform 2) KM=3 µM for cAMP (isoform 6)

This entry describes 7 isoforms produced by alternative splicing. [Align] [Select]

Note: Additional isoforms seem to exist.

Isoform 1 (identifier: P27815-1)

Also known as: PDE4A4; PDE4A4B; PDE46;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform 2 (identifier: P27815-2)

Also known as: TM3; PDE4A11;

The sequence of this isoform differs from the canonical sequence as follows:
     1-107: MEPPTVPSER...GGAGGGSSRR → MARPRGLGRI...LGRQAWAGAG

Isoform 3 (identifier: P27815-3)

Also known as: PDE4A7; PDE4A6;

The sequence of this isoform differs from the canonical sequence as follows:
     1-209: MEPPTVPSER...NVPVPSNKRS → MCPFPVTTV

Isoform 4 (identifier: P27815-4)

Also known as: PDE4A1; RD1;

The sequence of this isoform differs from the canonical sequence as follows:
     1-261: MEPPTVPSER...RSVSEMASHK → MPLVDFFCETCSKPWLVGWWDQ

Note: Isoform 4 has propensity for association with membranes. Ref.5 Ref.6 Ref.7

Isoform 5 (identifier: P27815-5)

Also known as: PDE4A8A; 2EL;

The sequence of this isoform differs from the canonical sequence as follows:
     1-367: MEPPTVPSER...KTDQEELLAQ → MVLPSDQGFKLLGNVLQGPEPYRLLTSGLRLHQ
     644-657: GFIDYIVHPLWETW → QARGIDGRAQGGFY
     658-886: Missing.

Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. Probably represents a non-functional splice isoform.

Isoform 6 (identifier: P27815-6)

Also known as: PDE4A10;

The sequence of this isoform differs from the canonical sequence as follows:
     1-107: MEPPTVPSER...GGAGGGSSRR → MRSGAAPRAR...RRHPPGRSVS

Isoform 7 (identifier: P27815-7)

Also known as: PDE4A8;

The sequence of this isoform differs from the canonical sequence as follows:
     1-107: MEPPTVPSER...GGAGGGSSRR → MKRSRSALSV...ISITRAENDS

Note: Predominantly cytoplasmic. Ref.5 Ref.6 Ref.7
