ProteinStartEndSwitch TypeSwitch SubtypeSwitch DescriptionInformation

DOC_CYCLIN_1 - Substrate recognition site that interacts with cyclin and thereby increases phosphorylation by cyclin/cdk complexes. Predicted proteins should have a CDK phosphorylation site. Also used by cyclin/cdk inhibitors.
RB_HUMAN873877SpecificityCompetitionThe docking sites for PP1 (e.g. Serine/threonine-protein phosphatase PP1-alpha catalytic subunit (PPP1CA)) and Cdk-Cyclins (e.g. Cyclin-A2 (CCNA2)) on Retinoblastoma-associated protein (RB1) overlap, which makes their binding to RB1 mutually exclusive. Hypophosphorylated RB1 blocks E2F-dependent transcription, while hyperphosphorylation inactivates RB1 as a repressor, thereby promoting cell cycle progression.

DOC_PP1 - Protein phosphatase 1 catalytic subunit (PP1c) interacting motif binds targeting proteins that dock to the substrate for dephosphorylation. The motif defined is [RK]{0,1}[VI][^P][FW].
RB_HUMAN872878SpecificityCompetitionThe docking sites for PP1 (e.g. Serine/threonine-protein phosphatase PP1-alpha catalytic subunit (PPP1CA)) and Cdk-Cyclins (e.g. Cyclin-A2 (CCNA2)) on Retinoblastoma-associated protein (RB1) overlap, which makes their binding to RB1 mutually exclusive.

NEK2_HUMAN380387BinaryPre‑translationalAlternative splicing removes the PP1-docking motif of Serine/threonine-protein kinase Nek2 (NEK2), abrogating binding to Serine/threonine-protein phosphatase PP1-alpha catalytic subunit (PPP1CA). Isoform Nek2A of Serine/threonine-protein kinase Nek2 (NEK2) is localised at centrosomes and causes centrosome splitting. Isoform Nek2B of Serine/threonine-protein kinase Nek2 (NEK2) is expressed at a different point in the cell cycle and required for assembly/maintenance of centrosomes.
