Figure 3. BE074730 is a trimera.

Figure 3

The origin of its 4–51st nt sequence (italicized and underlined) is unclear because it is completely matched not only to mtDNA but also to an NUMT on chromosome 1, as shown in the table copied from the UCSC browser. Its 52–221st nt sequence consists of two exons of the PRRC2A (also called BAT2) mRNA, with the downstream exon underlined; its real genomic origin is unclear, because this nRNA sequence belongs to a cluster of genes on chromosome 6 as shown in the table. The 230–357th nt sequence of this EST is part of the TMEM97 mRNA from chromosome 17. Actually, the 4–51st sequence also has homolog on chromosomes 2 and X, while the 230–357th sequence has homolog on chromosome 8. There is an 8-nt (boldfaced and italicized AAGCAACG) unmatchable gap between the 2nd and the 3rd partners.
