LIG_PCNA_2 - | |||||||
| ING1_HUMAN | 9 | 15 | Binary | Pre‑translational | Alternative splicing removes the PCNA-binding motif of Isoform Variant A of Inhibitor of growth protein 1 (ING1), abrogating binding to Proliferating cell nuclear antigen (PCNA). P33-ING1b (also known as Isoform Variant A of Inhibitor of growth protein 1 (ING1)) binds specially to PCNA, resulting in a major change in subcellular localisation and the import of this isoform into the nucleus. This is theorised to act by limiting access to the PCNA-binding domain but eventually it promotes apoptosis (though this may not be its physiological effect). | ||
LIG_PCNA_PIPBox_1 - The PCNA binding PIP box motif is found in proteins involved in DNA replication, repair and cell cycle control. | |||||||
| DPOD3_HUMAN | 456 | 465 | Binary | Physicochemical compatibility | Phosphorylation of S458 in the PCNA-binding motif of DNA polymerase delta subunit 3 (POLD3) by cAMP subfamily reduces the affinity of binding to the Proliferating cell nuclear antigen (PCNA) and decreases the processivity of the polymerase complex. | ||
| CDN1A_HUMAN | 144 | 153 | Binary | Physicochemical compatibility | 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 | 144 | 153 | Binary | Physicochemical compatibility | 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. | ||
