From: Formation of ultralong DH regions through genomic rearrangement
Bovine DH regions are characterized by repetitive sequences. a Nucleotide sequences of bovine DH regions in clusters 2–4. The RSS are in lowercase letters with the heptamer and nonamers in italics and underlined. The coding region of each DH is uppercase. Repeated sequences are colored red, blue and green. b Ungulate ultralong DH regions have different repeat lengths. The nucleotide sequences of polymorphic variants IGHD8–2*01 and IGHD8–2*02 for Bos taurus are compared to domestic yak (Bos grunniens; BosGru) and American bison (Bison bison; bison) orthologs of IGHD8–2
