title: Isolation and sequence analysis of a cDNA clone encoding the entire catalytic subunit of phosphorylase kinase.
abstract: Synthetic oligonucleotides have been used to isolate a 1.85 kb clone containing the full length coding sequence for the catalytic subunit of rabbit skeletal muscle phosphorylase kinase from a cDNA library constructed in lambda gt10. Sequence analysis of the clone predicted an amino acid sequence in agreement with a published primary structure. Inspection of the codon usage revealed a strong preference for G or C nucleotides at the third codon position as found for several other skeletal muscle proteins. This cDNA clone should facilitate identification of functional domains, including the calmodulin-binding site, and investigation of the molecular basis of X-linked phosphorylase kinase deficiencies.
