DNA encoding mammalian phosphodiesterases
View Patent ↗The present invention relates to novel purified and isolated nucleotide sequences encoding mammalian Ca 2+ /calmodulin stimulated phosphodiesterases (CaM-PDEs) and cyclic-GMP-stimulated phosphodiesterases (cGS-PDEs). Also provided are the corresponding recombinant expression products of said nucleotide sequences, immunological reagents specifically reactive therewith, and procedures for identifying compounds which modulate the enzymatic activity of such expression products.
1. An isolated and purified cGMP stimulated cyclic nucleotide phosphodiesterase polypeptide wherein said polypeptide comprises the amino acid sequence set forth in SEQ ID NO: 39.
2. An isolated and purified cGMP stimulated cyclic nucleotide phosphodiesterase polypeptide wherein said polypeptide comprises the amino acid sequence set forth in SEQ ID NO: 43.
3. An isolated and purified polypeptide product of the expression in a transformed prokaryotic or eukaryotic host cell of a polynucleotide sequence encoding a mammalian cGMP stimulated cyclic nucleotide phophodiesterase as set forth in SEQ ID NO: 39.
4. An isolated and purified polypeptide product of the expression in a transformed prokaryotic or eukaryotic host cell of a polynucleotide sequence encoding a mammalian cGMP stimulated cyclic nucleotide phophodiesterase as set forth in SEQ ID NO: 43.
