The LeuBase database is the resource molecular biology information of leukemia virus. LeuBase, organizes based on Open Reading Frames (ORF's) from partial and complete genome sequence from mammalian virus.

The Database of Leukemia Virus (LeuBase) is obtained from using the Bioinformatics Sequence Analysis (Comparative Genomics) Approach. The aim of LeuBase is to facilitate comparative genomics from various points of view such as genes and possible coding proteins information. This database containing information (gene's and protein's) of the Abelson murine leukemia virus, Feline leukemia virus, Friend murine leukemia virus, Gibbon ape leukemia virus, Molony murine leukemia virus, Rauscher murine leukemia virus, Bovine leukemia virus.

The LeuBase is developed to help the Biological and Medical science community for easy access all the information on the genes that are involved in Cancer Leukemia.
