S. pombe

• Unicellular archiascomycete• Diverged from S. cerevisiae 330- 1144 Ma • Size ~14 Mb, 3 chromosomes • No synteny• Data stored in GeneDB

Nomenclature Evolutionary relationships (orthology, paralogy,

protein family and domain)Functional annotation (Using GO, from literature

curation, functional transfer from orthologs, inferred electronically from protein family/domain)

Genetic mapping data (minimal, small amount, mostly linked to physical sequence data)
