ProteinMotifStartEndSwitch descriptionInformation

Type: Specificity Subtype: Domain hiding
A domain can be sterically masked by binding of an effector when there is a large difference in intrinsic affinity of the domain for different binding partners, or a large difference in the local abundance of these partners, thereby precluding further interactions of the domain. Binding of the masking molecule can be PTM-dependent or -independent.
NED4L_HUMANLIG_14-3-3_1465470Phosphorylation of Isoform Nedd4-2a of E3 ubiquitin-protein ligase NEDD4-like (NEDD4L) by Serine/threonine-protein kinase Sgk1 (SGK1) induces binding to 14-3-3 protein eta (YWHAH). This inhibits (whether allosterically or sterically is not known) interactions of NEDD4L via its WW domains with the PY motif in Amiloride-sensitive sodium channel subunit gamma (SCNN1G) (ENaC). As a result, ENaC does not get degraded and ENaC-mediated Na+ currents increase.

Type: Avidity‑sensing Subtype:
Multiple low-affinity interactions give rise to high-avidity interactions that have increased binding strength, with more than additive affinity.
SMAD3_HUMANLIG_WW_1181184CDK8/9 phosphorylates Mothers against decapentaplegic homolog 3 (SMAD3) at T179 and S208. Phosphorylation of T179 creates a binding site for the WW domain of Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1), while phosphorylation of S208 primes SMAD3 for phosphorylation of S204 by Glycogen synthase kinase-3 beta (GSK3B). The pS204-pS208 forms a binding site for the third WW domain of the E3 ubiquitin-protein ligase NEDD4-like (NEDD4L), whose second WW domain will displace the WW domain of PIN1 at the pT179-PY box site of SMAD3. This regulation couples SMAD3 activation to SMAD3 destruction in an ordered fashion. Dual phosphorylation of the two NEDD4L-binding sites mediates high-avidity binding of two WW domains of NEDD4L to SMAD3. See also switch details and switch details.

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.

This regulation couples SMAD3 activation to SMAD3 destruction in an ordered fashion. Phosphorylation of S208 in SMAD3 induces binding of the third WW domain of NEDD4L, while additional phosphorylation of S204 in SMAD3 further increases the affinity of this interaction.

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.
