The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 36 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
FunctionActivates HECT domain-containing E3 ubiquitin-protein ligases, including ITCH, NEDD4, NEDD4L, SMURF2, WWP1 and WWP2, and consequently modulates the stability of their targets. As a result, may control many cellular processes. Recruits ITCH, NEDD4 and SMURF2 to endosomal membranes. May modulate EGFR signaling.
Tissue specificityExpressed in brain, lung, heart, skeletal muscle, kidney, liver and placenta.
DomainThe PY (WW-binding) motifs are required for E3 ubiquitin-protein ligase activation and for ubiquitination.
Post-translational modificationsUbiquitinated by NEDD4 and ITCH. Also ubiquitinated by NEDD4L. Ubiquitination by NEDD4 or NEDD4L does not affect turnover. Undergoes transient tyrosine-phosphorylation following EGF stimulation, most probably catalyzed by SRC. Also phosphorylated by LYN and FYN.
