Type: Specificity Subtype: Competition | |||||||
Competitive binding of multiple binding partners to overlapping or adjacent, mutually exclusive interaction interfaces depends on local target protein abundance, which can be regulated by changing the expression level or subcellular localisation of the competitors, or by scaffolding. | |||||||
CDN1A_HUMAN | DOC_CYCLIN_1 | 19 | 22 | Cyclin-dependent kinase inhibitor 1 (CDKN1A) (p21) and the M-phase inducer phosphatase 1 (CDC25A) bind the same site on Cyclin proteins (e.g. G1/S-specific cyclin-E1 (CCNE1)), making their interactions mutually exclusive. | |||
MPIP1_HUMAN | DOC_CYCLIN_1 | 11 | 15 | Cyclin-dependent kinase inhibitor 1 (CDKN1A) (p21) and the M-phase inducer phosphatase 1 (CDC25A) bind the same site on Cyclin proteins (e.g. G1/S-specific cyclin-E1 (CCNE1)), making their interactions mutually exclusive. | |||
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. | |||||||
CDN1A_HUMAN | LIG_PCNA_PIPBox_1 | 144 | 153 | Phosphorylation of T145 in the PCNA-binding motif of Cyclin-dependent kinase inhibitor 1 (CDKN1A) by RAC-alpha serine/threonine-protein kinase (AKT1) inhibits binding to Proliferating cell nuclear antigen (PCNA). As a result, Cyclin-dependent kinase inhibitor 1 (CDKN1A) no longer inhibits Proliferating cell nuclear antigen (PCNA) and blocking of DNA replication is relieved. | |||
CDN1A_HUMAN | LIG_PCNA_PIPBox_1 | 144 | 153 | Phosphorylation of S146 in the PCNA-binding motif of Cyclin-dependent kinase inhibitor 1 (CDKN1A) by PKC subfamily inhibits binding to Proliferating cell nuclear antigen (PCNA). As a result, Cyclin-dependent kinase inhibitor 1 (CDKN1A) no longer inhibits Proliferating cell nuclear antigen (PCNA) and blocking of DNA replication is relieved. |
