Figure 1. The elephant IgH locus.

Figure 1

The elephant IgH locus is localized to scaffold 57. The length is approximately 2,974 kb from the most 5′ VH segment (VH2-112p) to the most 3′γ segment. Filled bars: potentially functional VH genes; open bars: VH pseudogenes: open bars and V-p; thin bars: truncated VH segments and V-t; DH: diversity genes; JH: joining genes; μ: IgM coding gene; δ: IgD remnant; and γ: IgG coding gene. VH and DH genes are numbered based on the families to which they belong and their positions in the locus. The number before the dash (VHn or DHn) indicates the family, while the number after dash represents the genomic position. JH genes are numbered based on the order of their locations in the locus. Double slashes indicate gaps >10 kb. Alpha and epsilon genes are not displayed on the map, but this does not imply their absence in the elephant IgH locus.
