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: 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.
