Identification and Cloning of Protein Kinase C Gene in C. elegans

S. Tomita, Y. Tabuse and J. Miwa

Protein kinase C (PKC) is considered to play an important role in 
the signal transduction of the eukaryotic system and proposed to be a 
primary target of TPA.  As a part of identifying PKC-like genes to 
understand the structural and functional relationship between tpa-1 
and PKC-like genes, we carried out Southern hybridization analysis 
using rabbit PKC cDNA(alpha,   and gamma forms kindly provided by Dr.  
Suzuki/Dr.  Ohno, Tokyo Metropolitan Institute of Medical Science) as 
a probe.  Five major bands of 6.0, 4.1, 3.2, 3.0, and 1.2kb and 
several minor bands were detected in HindIII -digested N2 DNA.  Also, 
to clone PKC-like genes we have screened both a cDNA library (a gift 
from Dr.  Kimble/ Dr.  Ahringer) and a genomic library with the same 
rabbit PKC DNA.  We have obtained 2 and 7 clones, respectively.  We 
are testing homology between these cloned DNA's and putative tpa-1 
cDNA as well as a rather long stretch of genomic DNA covering the 2.
4kb fragment associated with Tc1-induced TPA resistance.
