Recombinant Human ITCH/AIP4 Isoform 2 Protein, CF Summary

Purity
>90%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain
Activity

Recombinant Human ITCH/AIP4 is a HECT domain Ubiquitin ligase (E3) that functions downstream of a Ubiquitin-activating (E1) enzyme and a Ubiquitin-conjugating (E2) enzyme to conjugate Ubiquitin to substrate proteins. Reaction conditions will need to be optimized for each specific application. We recommend an initial Recombinant Human ITCH/AIP4 concentration of 0.1-0.5 μM.

Product Datasheets

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: ITCH/AIP4

The mammalian Itchy homolog, or ITCH, (also known as Atrophin-1-interacting protein 4 or AIP4) is a HECT domain class ubiquitin E3 ligase. ITCH/AIP4 ubiquitinates the phosphorylated form of Dishevelled protein and promotes its degradation via the Ubiquitin Proteasome System, thereby inhibiting canonical Wnt signaling. The absence of ITCH/AIP4 has been shown to cause severe autoimmune disease in mice. Recent studies have identified multisystem autoimmune disease and morphologic and developmental abnormalities in human patients with ITCH/AIP4 deficiency, thus underscoring the importance of ITCH/AIP4 in many cellular processes. This ligase may catalyze K29-, K48-, and/or K63-linked polyubiquitin chain formation on a variety of reported targets. This untagged, ITCH/AIP4 isoform 2 recombinant protein demonstrates strong autoubiquitination activity in vitro.
