germ-line V genes

germ-line V genes (VBASE2) provides a curated database of germ-line immunoglobulin variable (V) gene sequences from human and mouse to support analyses of antibody diversity and V(D)J rearrangements.

Key Features:

• Integration with Ensembl Genome Browser: Links V gene entries to genome sequence data and displays annotations within the Ensembl Genome Browser.
• EMBL-Bank References: Provides exhaustive references to EMBL nucleotide sequence database entries for each V gene, including information on V(D)J rearrangements.
• Cross-References to Immunogenetics Databases: Cross-references V gene entries to VBASE, IMGT, and Kabat to enable comparative analyses across resources.
• DAS Server Integration: Exposes V gene annotations via a Distributed Annotation System (DAS) server for visualization in genomic browsers.

Scientific Applications:

• Immunological Research: Characterizing the genetic basis of immune responses through analysis of germ-line V gene sequences and V(D)J rearrangements.
• Comparative Genomics: Comparing human and mouse immunoglobulin loci to study evolutionary relationships and locus organization.
• Antibody Repertoire Analysis: Supporting studies of antibody diversity and the origin of sequence variation in repertoires.
• Clinical Research: Informing investigations into autoimmune disease mechanisms and vaccine-related antibody responses via germ-line V gene data.

Methodology:

Extraction of germ-line V gene sequences from EMBL-Bank, integration with specialized immunogenetics resources (including cross-references to VBASE, IMGT, and Kabat), and dissemination of annotations via a DAS server for visualization in the Ensembl Genome Browser.
