The spontaneous l-isoaspartate protein modification has been observed to negatively affect protein function. However, this modification can be reversed in many proteins in reactions initiated by the protein-l-isoaspartyl (d-aspartyl) O-methyltransferase (PCMT1). It has been hypothesized that an additional mechanism exists in which l-isoaspartate-damaged proteins are recognized and proteolytically degraded. Herein, we describe the protein-l-isoaspartate O-methyltransferase domain-containing protein 1 (PCMTD1) as a putative E3 ubiquitin ligase substrate adapt
