ITCH is an E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. It regulates the transcriptional activity of several transcription factors, and probably plays an important role in the regulation of immune response. ITCH down-regulates Epstein-Barr virus LMP2A activity in B cell signaling, and has been shown to interact via its WW domains with DRPLA, NFE2 and CBLC. Other potential interaction partners include NOTCH1, OCLN, JUN and JUNB. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 0.03-0.1ug/ml Optimal dilutions to be determined by the researcher. Positive Control: Human Brain (Frontal Cortex) lysate Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
