ID:PDE1A_HUMAN DESCRIPTION: RecName: Full=Calcium/calmodulin-dependent 3',5'-cyclic nucleotide phosphodiesterase 1A; Short=Cam-PDE 1A; EC=3.1.4.17; AltName: Full=61 kDa Cam-PDE; AltName: Full=hCam-1; FUNCTION: Cyclic nucleotide phosphodiesterase with a dual- specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes. Has a higher affinity for cGMP than for cAMP. CATALYTIC ACTIVITY: Nucleoside 3',5'-cyclic phosphate + H(2)O = nucleoside 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: Type I PDE are activated by the binding of calmodulin in the presence of Ca(2+). SUBUNIT: Homodimer (By similarity). TISSUE SPECIFICITY: Several tissues, including brain, kidney, testes and heart. SIMILARITY: Belongs to the cyclic nucleotide phosphodiesterase family. PDE1 subfamily.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
