Abstract excerpt
An erroneous transcriptional process, known as molecular misreading, gives rise to an alternative transcript of the ubiquitin B (UBB) gene. This transcript encodes the protein UBB(+1), which comprises a ubiquitin moiety and a 19-aa C-terminal extension. UBB(+1) is found in affected neurons in neurodegenerative diseases and behaves as an atypical ubiquitin fusion degradation (UFD) proteasome substrate that is...
