Schematic representation of CRM1TR and CRM4TR arrays. a. Domain structure within CRM1TR monomers differs between locus I (L1) and II (LII). Excerpt of small regions from CRM1TR arrays at the two loci show that L1 repeats are homogenous with the structure S-IR-EB, while L2 repeats are more heterogeneous with the general structure S-IR*-EB/EA, where IR* indicates between 1 to 4 copies of internal repeat variants, and EB/EA indicates the two end sequence variants. The majority of L2 monomers have three copies of IR (i.e. IR.c1, IR.c2, and IRc3) that can be distinguished based on SNPs. b. CRM4TR arrays are homogenous and derived from an LTR-UTR segment of CRM4B. Figures were drawn using JunctionViewer software.
