Miscellaneousi

Miscellaneous

The adjacent MYZAP and POLR2M genes are part of a complex transcription unit. The respective transcripts derive from different promoters and are alternatively spliced. In human, some transcripts of the upstream promoter of MYZAP use exons of the downstream POLR2M gene.
