Biochemical Activity (Phosphorylation)
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.

CDK prevents Mcm2-7 helicase loading by inhibiting Cdt1 interaction with Orc6.
In Saccharomyces cerevisiae cells, B-type cyclin-dependent kinases (CDKs) target two origin recognition complex (ORC) subunits, Orc2 and Orc6, to inhibit helicase loading. We show that helicase loading by ORC is inhibited by two distinct CDK-dependent mechanisms. Independent of phosphorylation, binding of CDK to an "RXL" cyclin-binding motif in Orc6 sterically reduces the initial recruitment of the Cdt1/Mcm2-7 complex to ORC. ... [more]

| CLB5 ORC6 | Affinity Capture-Western 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. | Low | - | BioGRID | - | |
