DEG_APCC_DBOX_1 - An RxxL-based motif that binds to the Cdh1 and Cdc20 components of APC/C thereby targeting the protein for destruction in a cell cycle dependent manner |
CCNB1_HUMAN | 41 | 49 | Specificity | Domain hiding | 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. | details |
PTTG1_HUMAN | 60 | 68 | Specificity | Domain hiding | 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. | details |
DEG_APCC_KENBOX_2 - Motif conserving the exact sequence KEN that binds to the APC/C subunit Cdh1 causing the protein to be targeted for 26S proteasome mediated degradation. |
BUB1B_HUMAN | 303 | 307 | Specificity | Domain hiding | 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).
