Biochemical Activity (Ubiquitination)

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

Itch regulates p45/NF-E2 in vivo by Lys63-linked ubiquitination.

Lee TL, Shyu YC, Hsu TY, Shen CK

The hematopoietic-specific transcription factor p45/NF-E2 is an important transcriptional activator in the erythroid and megakaryocytic lineages. We describe the first in vivo evidence for the interaction between p45/NF-E2 and the E3 ubiquitin ligase Itch, and the subsequent ubiquitination of p45/NF-E2 by Itch. Interestingly, Itch suppressed the transactivation activity of p45/NF-E2 by adding a Lys63-linked polyubiquitin chain. Confocal microscopy revealed that ... [more]

Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.
