ProteinStartEndSwitch TypeSwitch SubtypeSwitch DescriptionInformation

LIG_PDZ_Class_1 - The C-terminal class 1 PDZ-binding motif is classically represented by a pattern like (ST)X(VIL)*
ADRB2_HUMAN408413BinaryPhysicochemical compatibilityPhosphorylation of S411 in the PDZ-binding motif of Beta-2 adrenergic receptor (ADRB2) by inhibits its interaction with the Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (SLC9A3R1) protein.

CTNB1_HUMAN776781BinaryAllosteryBinding of Ezrin (EZR) via its FERM domain to the EB domain of Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (SLC9A3R1) results in allosteric coupling to the second PDZ domain of Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (SLC9A3R1), which results in relief of the intramolecular interaction with the PDZ binding ligand, thereby increasing the affinity of the PDZ domain for other ligands, including Catenin beta-1 (CTNNB1).

NHRF1_HUMAN353358SpecificityDomain hidingBinding of Ezrin via its FERM domain to the EB domain of Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (SLC9A3R1) results in allosteric coupling to the second PDZ domain of SLC9A3R1. This relieves the intramolecular interaction with the SLC9A3R1 PDZ-binding ligand and increases the affinity of the PDZ domain for other ligands including Catenin beta-1 (CTNNB1).

CFTR_HUMAN14751480SpecificityCompetitionThe PDZ domains of Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (SLC9A3R1) and SH3 and multiple ankyrin repeat domains protein 2 (SHANK2) compete for the PDZ-binding motif of Cystic fibrosis transmembrane conductance regulator (CFTR). SLC9A3R1 positively regulates CFTR activity by recruiting a PKA-containing complex, while SH3 and multiple ankyrin repeat domains protein 2 (SHANK2) negatively affects CFTR activity by recruiting PDE4D.

CLCN3_HUMAN861866BinaryPre‑translationalAlternative splicing removes the PDZ-binding motif of Isoform ClC-3B of H(+)/Cl(-) exchange transporter 3 (CLCN3), abrogating binding to Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (SLC9A3R1). Isoform ClC-3B of H(+)/Cl(-) exchange transporter 3 (CLCN3) is expressed at the leading edge of membrane ruffles. The interaction of CLCN3 with SLC9A3R1 is important for localising outwardly rectifying chloride channels at the leading edge.

PGFRB_HUMAN11011106BinaryPhysicochemical compatibilityPhosphorylation of S1104 in the PDZ-binding motif of Platelet-derived growth factor receptor beta (PDGFRB) by Beta-adrenergic receptor kinase 1 (ADRBK1) inhibits binding to Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (SLC9A3R1). Binding of Platelet-derived growth factor receptor beta (PDGFRB) to Na(+)/H(+) exchange regulatory cofactor NHE-RF1 (SLC9A3R1) potentiates dimerisation and signalling of the receptor, while phosphorylation at S1104 desensitises the receptor.
