IG leader sequence logos:
TR leader sequence logos:
Leader sequences correspond to L-PART1 + L-PART2 artificially spliced. Sequences were extracted from IMGT/GENE-DB  with one sequence for each functional gene (allele *01). Number of gene sequences used to build the logo are indicated with, between parentheses, the number of subgroups to which the genes belong. Blanks in the sequences correspond to gaps introduced to maximize the alignment.
