The immunoglobulin kappa light-chain constant region gene (C kappa) has
been cloned and sequenced from five wild mouse species. Analysis of these
data has permitted an assessment of single-copy gene evolution during a
limited time period as defined by the genus Mus. Sequence conservation was
found to be as high (or higher) in the 5' and enhancer regions as in the
coding region. The pattern of substitutions throughout these genes suggests
that parallel evolution has occurred frequently and that substitutions at
replacement sites have not decreased significantly, owing to saturation
during this period of approximately 10 Myr. Phylogenetic relationships have
been determined among these wild species as well as among members of the
genus Rattus.
