Nucleotide sequence of a ras gene from the basidiomycete Coprinus cinereus.

The basidiomycete Lentinus edodes (Le.) ras gene (or its cDNA clone) [Hori et al., Gene 105 (1991) 91-96] was utilized to identify and clone the corresponding gene (Cc.ras)-containing genomic fragment from the basidiomycete, Coprinus cinereus. Cc.ras encodes 215 amino acids (aa) interrupted by six small introns. The deduced Cc.RAS protein exhibits significant homology (84.7% identical) to the Le.RAS protein (217 aa) in size and aa sequence.
