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.
B2L11_HUMANDEG_SCF_TRCP1_29398Alternative splicing removes the extended SCF-TrCP degron motif of Bcl-2-like protein 11 (BCL2L11), abrogating binding to F-box/WD repeat-containing protein 1A (BTRC). Upon mitogen survival signals, RPS6KA1 and RPS6KA2 kinases are up-regulated and rapidly phosphorylate the three serines of Isoform Bim(EL) of Bcl-2-like protein 11 (BCL2L11). This facilitates the binding of betaTrCP and subsequent ubiquitination and degradation of Isoform Bim(EL) of Bcl-2-like protein 11 (BCL2L11).
REST_HUMANDEG_SCF_TRCP1_210081013Alternative splicing removes the beta-TrCP-binding degron of RE1-silencing transcription factor (REST), abrogating binding to F-box/WD repeat-containing protein 1A (BTRC), and therefore altering the half-life of the variant. Up-regulation of the protein isoform without the degron has been linked to cancer.

Type: Specificity Subtype: Altered binding specificity
The balance of the competition for overlapping or adjacent, mutually exclusive interaction interfaces is tipped in favor of one of the interactors by PTM-dependent modulation of the intrinsic affinity of a binding region. Multiple, successive PTMs allow sequential switching of different binding partners in an ordered manner by step-wise alteration of binding specificity.
YAP1_HUMANDEG_SCF_TRCP1_2383387Phosphorylation of Yorkie homolog (YAP1) at S381 by Serine/threonine-protein kinase LATS1 (LATS1) (a key regulator of the Hippo Pathway) primes the sequence for phosphorylation by Casein kinase I isoform epsilon (CSNK1E) at S384 and S387. This targets YAP1 to the SCF ubiqutin ligase complex, F-box/WD repeat-containing protein 1A (BTRC), which marks is YAP1 for subsequent degradation by the proteasomal system. N.B. Serine/threonine-protein kinase LATS2 (LATS2) can replace LATS1 and Casein kinase I isoform delta (CSNK1D) can replace CSNK1E
