Type: Cumulative Subtype: Rheostatic | |||||||
Rheostatic switches gradually alter the affinity of a motif for a single binding partner by addition of multiple PTMs that additively contribute to this modulation. Additional modifications can either strengthen or weaken an interaction. | |||||||
MK67I_HUMAN | LIG_FHA_2 | 238 | 244 | Phosphorylation of T238 in MKI67 FHA domain-interacting nucleolar phosphoprotein (MKI67IP) by Cyclin-dependent kinase 1 (CDK1) primes for phosphorylation of T234 by Glycogen synthase kinase-3 beta (GSK3B), which primes for phosphorylation of S230 by Glycogen synthase kinase-3 beta (GSK3B). Triple-phosphorylated hNIFK (MKI67 FHA domain-interacting nucleolar phosphoprotein (MKI67IP)) binds strongly to Antigen KI-67 (MKI67). See also switch details | |||
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. | |||||||
