The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 10 µg/ml.
Use a concentration of 20 µg/ml.
Use a concentration of 1 - 2 µg/ml. Predicted molecular weight: 100 kDa.
FunctionInhibitor of the E3 ubiquitin-protein ligase ITCH. Acts by interacting with the second WW domain of ITCH, leading to compete with ITCH's substrates and impairing ubiquitination of substrates.
Tissue specificityDetected in heart, lung, brain, liver, skeletal muscle, pancreas, kidney, spleen, testis and ovary.
Sequence similaritiesBelongs to the N4BP1 family.
Post-translational modificationsMonoubiquitinated by NEDD4. Polyubiquitinated, leading to its degradation by the proteasome. Sumoylated by SUMO1, abrogating polyubiquitination and subsequent degradation. Desumoylated by SENP1, leading to accumulation in PML nuclear bodies. Phosphorylated upon DNA damage, probably by ATM or ATR.
Cellular localizationNucleus > nucleolus. Nucleus > PML body. Primarily localizes to the nucleolus. Also localizes to the PML nuclear bodies, when desumoylated.
