Switches

This ELM instance is part of the following 3 switching mechanisms annotated at the switches.ELM resource:

SWTI000685:

Binding of the second KEN-box motif of Mitotic checkpoint serine/threonine-protein kinase BUB1 beta (BUB1B), a subunit of the Spindle Assembly Checkpoint (SAC), to the substrate recruitment site of Cell division cycle protein 20 homolog (CDC20), the substrate recognition subunit of the Anaphase Promoting Complex/Cyclosome (APC/C), blocks binding of the Cdc20 substrate G2/mitotic-specific cyclin-B1 (CCNB1). As a result, G2/mitotic-specific cyclin-B1 (CCNB1) is not targeted for proteasomal degradation until metaphase, when the SAC is inhibited. Destruction of G2/mitotic-specific cyclin-B1 (CCNB1) is required for progression to the anaphase of the cell cycle.
SWTI000686:

Binding of the second KEN-box motif of Mitotic checkpoint serine/threonine-protein kinase BUB1 beta (BUB1B), a subunit of the Spindle Assembly Checkpoint (SAC), to the substrate recruitment site of Cell division cycle protein 20 homolog (CDC20), the substrate recognition subunit of the Anaphase Promoting Complex/Cyclosome (APC/C), blocks binding of the Cdc20 substrate Securin (PTTG1). As a result, Securin (PTTG1) is not targeted for proteasomal degradation until metaphase, when the SAC is inhibited. Destruction of Securin (PTTG1) is required for progression to the anaphase of the cell cycle.
