[Introduction]

V BASE is a comprehensive directory of all human germline variable region sequences compiled from over a thousand published sequences, including those in the current releases of the Genbank and EMBL data libraries. The database has been developed over several years at the MRC Centre for Protein Engineering (Cambridge, UK) as an extension of our work on the sequencing and mapping of human antibody genes and a user friendly tool for their analysis. V BASE has recently been upgraded (1 December 1997) to include nucleotide alignments for all functional segments, scale maps of all human V gene loci and a number of other new services. These include a new version of the DNAPLOT alignment software which enables rearranged genes to be reliably assigned to their closest germline counterparts using the latest germline sequence data (including data from the recently completed VL and D segment sequencing projects) and tables which denote the numbers of functional segments (which belong to each V gene family), the numbers of functional segments cut by different restriction enzymes and PCR primers for amplifying rearranged V genes. In addition, all the sequences in V BASE can now be browsed.

All the germline V gene sequences in the database have been carefully checked against their original citation and against their EMBL/Genbank entry. V BASE is now updated regularly to include all the latest germline sequence data and is used by over a thousand immunologists and geneticists worldwide. For further information on the the main services click on the following: amino acid and nucleotide sequence alignments, scale maps of the human immunoglobulin loci or sequence alignment software (DNAPLOT)


[Amino acid and nucleotide alignments]

Amino acid and nucleotide sequence alignments have been compiled for all functional V, D and J segments (including all the mapped leader sequences). These can be used to design family or segment specific PCR primers and/or oligonucleotide probes. For some segments there are multiple alleles. In these cases, positions with allelic differences are underlined and the specific changes are shown beneath the alignments. For all sequences, links to a master reference list are provided. The following example is an alignment of all the functional VKI segments taken from V BASE:

[Maps]

V BASE also provides scale maps for the VH, VK, VL and D regions. These denote the positions of all the functional and non-functional segments together with the locations (and frequencies) of any insertions/deletions that have been characterised for these loci. The following example is a scale map of the human D region taken from V BASE:

[Alignment software]

In collaboration with Werner Müller and Hans-Helmar Althaus, the DNAPLOT alignment package has been specially adapted for the alignment of rearranged nucleotide sequences to their closest human germline V, D and J segment precursors. The alignment is to all known human germline sequences (not just those that have been mapped) and includes all known alleles of all germline V, D and J segments.

Simply paste the rearranged sequence into the box and hit 'Start'. Your sequence will be returned aligned to the closest VH, D and JH segments if it was a VH gene, the closest VK and JK segments if it was a VK gene or the closest VL and JL segments if it was a VL gene. For the V segments the top five alignments are given and for the D and J segments the top three alignments are given (where there are identical scores, the germline sequences are ranked as to whether they have been confirmed by independently laboratories and/or whether they have been mapped).

For each germline sequence a link to the EMBL database and the map position (if known) is provided. The alignment can be returned numbered and padded according to the Kabat or Chothia nomenclatures and the software will tell you whether the rearrangement was in or out of frame. In addition, the VH, VK or VL segment family and the reading frame of the D segment (if a VH gene) are provided. The following is an example of a VH gene aligned to V BASE using this DNAPLOT interface:
