Ready-to-use ELISA kits are available for the detection of Pkgi, an alias of the protein, protein kinase cGMP-dependent 1. The official gene symbol is PRKG1. The kits can detect several species variants of the protein, including: human and mouse. The protein, with a mass of 76.4 kDa and length of 671 residues, is reported to be cytoplasmic. It is a member of the Protein kinase superfamily, AGC Ser/Thr protein kinase family, cGMP subfamily and may be known by other names, including: PRKG1B, PKG1, AAT8, protein kinase cGMP-dependent type I, protein kinase cGMP-dependent regulatory type I beta, and cGMP-dependent protein kinase 1, and cGK.
