  • Serine/theonine protein kinase
    Patent number: 6358720
    Abstract: A mouse CDNA encoding a protein comprising a serine/threonine protein kinase region was isolated by effecting PCR using a synthetic DNA corresponding to the kinase-conserved region as a primer and a rat cDNA as a template. A mouse cDNA library was screened using the DNA fragment thus obtained as a probe. The multiple human and mouse cDNAs having the similar structure to the isolated mouse cDNA were successfully isolated based on the sequence of the isolated mouse cDNA. An antisense DNA against the isolated mouse cDNA was synthesized, and its effect on a nerve cell was studied to confirm that the antisense DNA inhibits axonal elongation.
