  • Function
    E3 ubiquitin ligase. Regulates proteasomal degradation of cardiac troponin I/TNNI3 and probably of other sarcomeric-associated proteins. May play a role in striated muscle atrophy and hypertrophy by regulating an anti-hypertrophic PKC-mediated signaling pathway. May regulate the organization of myofibrils through TTN in muscle cells.
  • Tissue specificity
    Muscle specific. Selectively expressed in heart and skeletal muscle. Also expressed in the iris.
  • Pathway
    Protein modification; protein ubiquitination.
  • Sequence similarities
    Contains 1 B box-type zinc finger.
    Contains 1 COS domain.
    Contains 1 RING-type zinc finger.
  • Developmental stage
    Expressed throughout all developmental stages.
  • Domain
    The RING-type zinc finger mediates interaction with SUMO2 and localization to the nucleus. Also required for the E3 ubiquitin ligase activity.
  • Cellular localization
    Cytoplasm. Nucleus. Localizes to the M- and Z-lines in skeletal muscle. Colocalizes with TNNI3 in myocytes.
