What's a GeneRIF?

The anaphase-promoting complex/cyclosome (APC/C) is suppressed by the small pseudosubstrate inhibitor Acm1. Acm1 D-box extension inhibits reaction processivity by perturbing the normal interaction with Doc1/Apc10. These results reveal a simple, elegant mode of pseudosubstrate inhibition that combines high-affinity activator binding with specific disruption of Doc1/Apc10 function in processive ubiquitylation.

the structure of an Acm1-Cdh1 complex
Title: Insights into degron recognition by APC/C coactivators from the structure of an Acm1-Cdh1 complex.
Cells lacking Acm1 have defects in nuclear positioning and spindle morphology during mitosis.
Title: Acm1 contributes to nuclear positioning by inhibiting Cdh1-substrate interactions.
unique property of the Acm1 degron sequences results from an unusually high affinity interaction with the substrate receptor site on the WD40 domain of Cdh1 that may serve both to promote APC inhibition and protect Acm1 from destruction.
Title: Unique D box and KEN box sequences limit ubiquitination of Acm1 and promote pseudosubstrate inhibition of the anaphase-promoting complex.
Cdc28 serves dual roles in inhibiting Cdh1-dependent anaphase-promoting complex (APC) activity during the cell cycle: stabilization of the Cdh1 inhibitor Acm1 and direct phosphorylation of Cdh1 to prevent its association with the APC.
Title: Pseudosubstrate inhibition of the anaphase-promoting complex by Acm1: regulation by proteolysis and Cdc28 phosphorylation.
Data show that in budding yeast the activation of APC(Cdh1) is controlled in part by destruction of the Cdh1 inhibitor Acm1.
Title: Modulation of the mitotic regulatory network by APC-dependent destruction of the Cdh1 inhibitor Acm1.
the opposing actions of Cdc28 and Cdc14 are primary factors limiting Acm1 to the interval from G(1)/S to late mitosis and are capable of establishing APC-independent expression patterns similar to APC substrates
Title: Cdc28 and Cdc14 control stability of the anaphase-promoting complex inhibitor Acm1.
Acm1 and Bmh1/Bmh2 constitute a specialized inhibitor of anaphase-promoting complex/CCdh1.
Title: Acm1 is a negative regulator of the CDH1-dependent anaphase-promoting complex/cyclosome in budding yeast.
