title: Computational and experimental analysis reveals a novel Src family kinase in the C. elegans genome.
abstract: BACKGROUND
  The complete genomes of a number of organisms have already been sequenced. However, the vast majority of annotated genes are derived by gene prediction methods. It is important to not only validate the predicted coding regions but also to identify genes that may have been missed by these programs.
  
  
  METHODS
  We searched the entire C.elegans genomic sequence database maintained by the Sanger Center using human c-Src sequence in a TBLASN search. We have confirmed one of the predicted regions by isolation of a cDNA and carried out a phylogenetic analysis of Src kinase family members in the worm, fly and several vertebrate species.
  
  
  RESULTS
  Our analysis identified a novel tyrosine kinase in the C.elegans genome that contains functional features typical of the Src family kinases that we have designated as Src-1. The open reading frame contains a conserved N-terminal myristoylation site and a tyrosine residue within the C-terminus that is crucial for regulating the activity of Src kinases. Our phylogenetic analysis of Src family members from C. elegans, Drosophila and other higher organisms revealed a relationship among Src kinases from C. elegans and Drosophila.
