WB Use a concentration of 1 µg/ml. Detects a band of approximately 40 kDa (predicted molecular weight: 40 kDa).
IHC-P Use a concentration of 5 µg/ml.


  • FunctionE3 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 specificityMuscle specific. Selectively expressed in heart and skeletal muscle. Also expressed in the iris.
  • PathwayProtein modification; protein ubiquitination.
  • Sequence similaritiesContains 1 B box-type zinc finger.
    Contains 1 COS domain.
    Contains 1 RING-type zinc finger.
  • Developmental stageExpressed throughout all developmental stages.
  • DomainThe RING-type zinc finger mediates interaction with SUMO2 and localization to the nucleus. Also required for the E3 ubiquitin ligase activity.
  • Cellular localizationCytoplasm. Nucleus. Localizes to the M- and Z-lines in skeletal muscle. Colocalizes with TNNI3 in myocytes.

    Additional bands at : 110 kDa,30 kDa,55 kDa. We are unsure as to the identity of these extra bands.
  • IHC image of ab77577 staining in Mouse Skeletal Muscle formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab77577, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
