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.

529		Binding of meiRNA meiotic non-coding RNA (meiRNA) to the RRM domains of Meiosis protein mei2 (mei2) is essential for promotion of premeiotic DNA synthesis and meiosis I and is blocked by Pat1-mediated phosphorylation-induced binding of the 14-3-3 protein DNA damage checkpoint protein rad24 (rad24) to 2 14-3-3 binding motifs in mei2
details

Type: Avidity‑sensing Subtype:
Multiple low-affinity interactions give rise to high-avidity interactions that have increased binding strength, with more than additive affinity.
RAF1_HUMANLIG_14-3-3_1256261Phosphorylation of two 14-3-3-binding motifs in RAF proto-oncogene serine/threonine-protein kinase (RAF1) in response to growth factors induces high-avidity binding to dimeric 14-3-3 protein zeta/delta (YWHAZ), with pS621 being the high-affinity interaction site. This interaction locks RAF proto-oncogene serine/threonine-protein kinase (RAF1) in an inhibited conformation.
details
RAF1_HUMANLIG_14-3-3_1618623Phosphorylation of two 14-3-3-binding motifs in RAF proto-oncogene serine/threonine-protein kinase (RAF1) in response to growth factors induces high-avidity binding to dimeric 14-3-3 protein zeta/delta (YWHAZ), with pS621 being the high-affinity interaction site. This interaction locks RAF proto-oncogene serine/threonine-protein kinase (RAF1) in an inhibited conformation.
details
MEI2_SCHPOLIG_14-3-3_1435440Phosphorylation of two 14-3-3-binding motifs in Meiosis protein mei2 (mei2) by Negative regulator of sexual conjugation and meiosis (ran1) induces high-avidity binding to dimeric DNA damage checkpoint protein rad24 (rad24), with pT527 being the high-affinity interaction site.
details
MDM4_HUMANLIG_14-3-3_1364369Optimal binding of 14-3-3 dimer to Hdmx in response to DNA damage requires phosphorylation of two 14-3-3-binding motifs by Chk2 kinase. Binding of 14-3-3 dimer is involved in inactivation of Hdmx, a negative regulator of p53, in response to DNA damage.
details
FOXO4_HUMANLIG_14-3-3_12934Phosphorylation of two 14-3-3-binding motifs in Foxo4 by PKB induces binding of 14-3-3 dimer. In the nucleus, this blocks binding to DNA, while in the cytoplasm it blocks reimport of Foxo4 into the nucleus by blocking its Nuclear Localisation Signal (NLS). Since binding of 14-3-3 to a single motif occurs with an affinity similar to the affinity of Foxo4 for DNA, multivalent binding of 14-3-3 dimer is required for efficient inhibition of DNA binding.
details

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.
BAD_RATLIG_14-3-3_1134139Phosphorylation of S137 by RAC-alpha serine/threonine-protein kinase (Akt1) in the 14-3-3-binding motif of Bcl2 antagonist of cell death (Bad) induces binding to the 14-3-3 protein beta/alpha (YWHAB) protein. This interaction inhibits the pro-apoptotic activity of Bcl2 antagonist of cell death (Bad).
details
MT_POVM3LIG_14-3-3_1254259Phosphorylation of S257 in the 14-3-3-binding motif of Middle T antigen induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein.
details
ATX1_HUMANLIG_14-3-3_1772777Phosphorylation of S775 by RAC-alpha serine/threonine-protein kinase (AKT1) in the 14-3-3-binding motif of Ataxin-1 (ATXN1) induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein.
details
M3K5_HUMANLIG_14-3-3_1963968Phosphorylation of S966 in the 14-3-3-binding motif of Mitogen-activated protein kinase kinase kinase 5 (MAP3K5) induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein. This interaction inhibits the pro-apoptotic activity of Mitogen-activated protein kinase kinase kinase 5 (MAP3K5).
details
RAF1_HUMANLIG_14-3-3_1256261Phosphorylation of S257 in the 14-3-3-binding motif of RAF proto-oncogene serine/threonine-protein kinase (RAF1) abolishes binding of the motif, phosphorylated at S259, to 14-3-3 protein zeta/delta (YWHAZ).
details
YAP1_MOUSELIG_14-3-3_1109114Phosphorylation of S112 in the 14-3-3 binding motif of Yorkie homolog (Yap1) induces binding to the 14-3-3 protein epsilon (Ywhae) protein. 14-3-3 retains phosphorylated YAP in the cytosol, negatively regulating its function.
details
WWTR1_HUMANLIG_14-3-3_18691Phosphorylation of S89 in the 14-3-3-binding motif of WW domain-containing transcription regulator protein 1 (WWTR1) induces binding to 14-3-3 protein epsilon (YWHAE), retaining phosphorylated WWTR1 in the cytosol, negatively regulating its function.
details
BAD_MOUSELIG_14-3-3_1133138Phosphorylation of S136 in Bcl2 antagonist of cell death (Bad) by RAC-alpha serine/threonine-protein kinase (Akt1) in response to survival and growth signals such as Interleukin-3 (Il3) induces binding to 14-3-3 protein theta (Ywhaq). Binding of 14-3-3 protein theta (Ywhaq) results in dissociation of Bcl2 antagonist of cell death (Bad) from Bcl-2-like protein 1 (Bcl2l1), and thereby inhibits the pro-apoptotic activity of Bcl2 antagonist of cell death (Bad) by allowing liberated Bcl-2-like protein 1 (Bcl2l1) to exert its anti-apoptotic effect on pro-apoptotic proteins like Apoptosis regulator BAX (Bax).
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.
ATX1_HUMANLIG_14-3-3_1772777Phosphorylation of S775 switches binding specificity of Ataxin-1 (ATXN1) from the splicing factor Splicing factor U2AF 65 kDa subunit (U2AF2) to 14-3-3 proteins (e.g. 14-3-3 protein zeta/delta (YWHAZ)). While association with the spliceosome protects ATXN1 from self-association, its phosphorylation-dependent recruitment to 14-3-3 proteins (e.g. YWHAZ) might result in aggregation.
