Protein attributes
| Sequence length | 736 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes By similarity. |
| 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 By similarity. |
| Enzyme regulation | Expression is under the control of follicle-stimulating hormone and cAMP. Inhibited by rolipram. |
| Pathway | Purine metabolism; 3',5'-cyclic AMP degradation; AMP from 3',5'-cyclic AMP: step 1/1. |
| Tissue specificity | Widely expressed. Isoform 3 expressed in brain, heart, lung and liver. Isoform 4 expressed in liver and brain. Ref.5 Ref.10 |
| Induction | In Sertoli cells, induced by FSH. In the pineal gland, exhibits night/day variations with a 7-fold increased expression at night. Up-regulation is due to a large degree to the release of norepinephrine from nerve terminals in the pineal gland and cAMP signaling pathway. Ref.1 Ref.10 |
| Sequence similarities | Belongs to the cyclic nucleotide phosphodiesterase family. PDE4 subfamily. |
| Biophysicochemical properties | Kinetic parameters: Vmax values for isoforms 2, 3 and 4 relative to isoform 1 are 3.8, 1.6 and 2.1. |
Ontologies
Alternative products
| This entry describes 5 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: P14646-3) Also known as: PDE4B1; 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: P14646-2) Also known as: PDE4B2; The sequence of this isoform differs from the canonical sequence as follows: 1-172: Missing. 173-211: LASLRIVRNN...QAPVTRVSLQ → MKEQGGTVSG...PNYLSVCLFA | ||||||
| Isoform 3 (identifier: P14646-1) Also known as: PDE4B3; The sequence of this isoform differs from the canonical sequence as follows: 1-93: MKKSRSVMAV...SIAITTVSQE → MTAKNSSKEL...QRRRFTVAHT | ||||||
| Isoform 4 (identifier: P14646-4) Also known as: PDE4B4; The sequence of this isoform differs from the canonical sequence as follows: 1-93: MKKSRSVMAV...SIAITTVSQE → MLHVNDLPPPRRHSWI | ||||||
| Note: Activated by phosphorylation at Ser-56. Mutagenesis of Ser-56 abolishes activation. | ||||||
| Isoform 5 (identifier: P14646-5) The sequence of this isoform differs from the canonical sequence as follows: 1-93: MKKSRSVMAV...SIAITTVSQE → MTAKNSSKEL...QRRRFTVAHT 710-736: VIDPENRDSLEETDIDIATEDKSLIDT → KPCHAANGLALPVGGGNAASTQPRCGHV | ||||||
| Note: No experimental confirmation available. |
