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.
INSR_HUMANLIG_SH2_STAT513611364PIP3 (1-phosphatidyl-1D-myo-inositol 3,4,5-trisphosphate), a product of PI3-kinase, binds to the SH2 domains of PI3K (Phosphatidylinositol 3-kinase regulatory subunit alpha (PIK3R1)) and thereby blocks its interaction with tyrosine-phosphorylated SH2 motif containing proteins.

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.
INSR_HUMANLIG_PTB_Phospho_1993999Phosphorylation of Y999 in the PTB-binding motif of Insulin receptor (INSR) induces binding to the SHC-transforming protein 1 (SHC1) protein.
