Detailed post-FANTOM meeting analysis of sequences containing motifs
MD00121,
MD00129, MD00137 and MD00139 revealed that the DECODER predicted ORFs
including the motif regions overlap with B2, B1 intracisternal
A-particle LTR,
and mammalian apparent LTR-retrotransposon repeat elements,
respectively. The
four motifs are therefore false positives and the sequences constitute
transcribed repeats or repeat containing transcripts.
