Recombinant Human His6-Ataxin UIM Domains Protein, CF Summary
The Ubiquitin-interacting Motif (UIM) is an alpha-helical Ubiquitin-binding domain found in many proteins that recognizes and traffics ubiquitinated cargo (1,2). Ataxin-3, a deubiquitinating enzyme that contains three consecutive UIM motifs (amino acids (aa) 224-243, 244-263, 331-348), functions as a mixed lineage, chain editing enzyme that recognizes and binds K48-linked and K63-linked poly-Ubiquitin chains (3-5). The UIM domain of Ataxin-3 (aa 224-348) preferentially interacts with four or more Ubiquitin units of K48-linked or K63-linked poly-Ubiquitin chains or ubiquitinated substrates that contain these linkages (4,6,7).
This protein can be used for the isolation and identification of K48-linked (preferentially) or K63-linked poly-Ubiquitin chains or ubiquitinated substrates that contain these linkages. This protein is His-tagged which allows for metal chelate affinity purification and also allows for convenient immuno-detection of conjugates using His6-specific antibodies.
