		Technical Data
A4156-17A	Atrophin-1 Interacting Protein 4, NT (AIF4, ITCH, E3 Ubiquitin-protein Ligase Itchy Homolog, AIP4, NAPP1, NFE2-associated Polypeptide 1, NAPP1)

Description:
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 ELISA, Western Blot, and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
ELISA: 1:1,000
Western Blot: 1:100-1:500
Immunohistochemistry: 1:50-1:100
Optimal dilutions to be determined by the researcher.
