dbSTS is a new NCBI resource that contains sequence and mapping data on short genomic landmark sequences or Sequence Tagged Sites (Olson et al., 1989).
Although dbSTS sequences are to be incorporated into the new STS Division of GenBank , annotation in dbSTS is more comprehensive and includes detailed contact information about the contributors, experimental conditions and genetic map locations. In addition, NCBI periodically updates putative homology assignments using the BLAST family of programs (Altschul et al., 1994).
