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. |
| MPIP2_HUMAN | 191 | 195 | Binary | Pre‑translational | Alternative splicing removes the APC/C KEN-box degron motif of M-phase inducer phosphatase 2 (CDC25B), abrogating binding to Fizzy-related protein homolog (FZR1). The motif-lacking Isoform CDC25B2 of M-phase inducer phosphatase 2 (CDC25B) is not degraded during mitosis, unlike other isoforms. | details |
| 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). 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 |

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 |
| ACM1_YEAST | 97 | 101 | Specificity | Domain hiding | The KEN-box motif of APC/C-CDH1 modulator 1 (ACM1) binds to the substrate recruitment site of APC/C activator protein CDH1 (CDH1), the substrate recognition subunit of the Anaphase Promoting Complex/Cyclosome (APC/C), and thereby blocks recruitment, and subsequent targeting for proteasomal degradation, of the Cdh1 substrate G2/mitotic-specific cyclin-2 (CLB2). Degradation of G2/mitotic-specific cyclin-2 (CLB2) is required for mitotic exit and maintenance of the G1 phase of the cell cycle and is allowed by Cdc20-dependent degradation of APC/C-CDH1 modulator 1 (ACM1) in anaphase. | details |
