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. | |||||||
JUN_HUMAN | MOD_GSK3_1 | 236 | 243 | Phosphorylation of Transcription factor AP-1 (JUN) at S243 primes the protein for phosphorylation at T239 by Glycogen synthase kinase-3 beta (GSK3B). | |||
JUN_HUMAN | DOC_WW_Pin1_4 | 60 | 65 | Phosphorylation of S63 in the Pin1-binding motif of Transcription factor AP-1 (JUN) induces binding to the Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1) protein. | |||
JUN_HUMAN | DOC_WW_Pin1_4 | 70 | 75 | Phosphorylation of S73 in the Pin1-binding motif of Transcription factor AP-1 (JUN) induces binding to the Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1) protein. | |||
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. | |||||||
JUN_HUMAN | MOD_GSK3_1 | 236 | 243 | Transcription factor AP-1 (JUN) is primed by an unknown kinase for phosphorylation by Glycogen synthase kinase-3 beta (GSK3B), which targets JUN to the SCF ubiquitin ligase complex, F-box/WD repeat-containing protein 7 (FBXW7) that marks JUN for degradation. In v-Jun (Viral jun-transforming protein (JUN)) the residue corresponding to S243 is mutated to phenylalanine, which protects v-Jun (JUN) from degradation. | |||
