Our Abpromise guarantee covers the use of ab52174 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use at an assay dependent concentration.
ELISA 1/20000.
WB 1/1000. Detects a band of approximately 17 kDa (predicted molecular weight: 17 kDa).


  • FunctionInhibitor of PPP1CA. Has over 1000-fold higher inhibitory activity when phosphorylated, creating a molecular switch for regulating the phosphorylation status of PPP1CA substrates and smooth muscle contraction.
  • Tissue specificityIsoform 1 is detected in aorta and testis. Isoform 2 is detected in aorta.
  • Sequence similaritiesBelongs to the PP1 inhibitor family.
  • Cellular localizationCytoplasm.
