hAG-2 and hAG-3 show close homology at the protein level and are adjacent to each other at chromosome position 7p21. (A) Protein sequence alignment of hAG-2 and hAG-3 (DNAStar MegAlign program–Jotun Hein alignment). The boxed regions on the hAG-3 sequence indicate exact amino-acid matches of hAG-3 with hAG-2. (B) Diagram illustrating the genomic locations, transcriptional orientation, and exon structures of hAG-2 and hAG-3 on chromosome 7p21.
