Type: Binary Subtype: Physicochemical compatibility | |||||||
PTM of a residue in a motif or in its flanking regions alters the physicochemical and/or structural compatibility of the motif with its binding partner. This can either induce or enhance an interaction, or result in inhibition or even abrogation of an interaction. | |||||||
MPIP2_HUMAN | LIG_PLK | 49 | 51 | Phosphorylation of S50 in the PLK-docking motif of M-phase inducer phosphatase 2 (CDC25B) by Cyclin-dependent kinase 1 (CDK1)-Cyclin AB subfamily generates a recruitment site for Serine/threonine-protein kinase PLK1 (PLK1), which then phosphorylates and activates M-phase inducer phosphatase 2 (CDC25B). | |||
MPIP2_HUMAN | LIG_14-3-3_3 | 320 | 325 | Phosphorylation of S321 in the 14-3-3-binding motif of M-phase inducer phosphatase 2 (CDC25B) by Cyclin-dependent kinase 1 (CDK1) during mitosis abolishes binding of the motif, phosphorylated at S323, to 14-3-3 protein beta/alpha (YWHAB), thereby maintaining active Cdc25B. | |||
Type: Binary Subtype: Pre‑translational | |||||||
Pre-translational mechanisms such as alternative splicing, alternative promoter-usage and/or RNA editing result in inclusion or removal of exons that contain an entire or partial motif. | |||||||
MPIP2_HUMAN | DEG_APCC_KENBOX_2 | 191 | 195 | 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. |
