PDZ domain of signal-induced proliferation-associated protein 1 (SIPA1), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of SIPA1, and related domains. The Rap-GTPase activating protein SIPA1 (also known as GTPase-activating protein Spa-1, p130 SPA1) is a metastasis promoter; a polymorphism in a region of the Sipa1 gene encoding the PDZ domain is associated with metastasis. The SIPA1 PDZ domain binds ribosomal RNA processing 1 homolog B (Rrp1b). SIPA1 also forms a complex with water channel aquaporin-2 (AQP2) and plays a role in trafficking of AQP2, targeted positioning of which strictly regulates body water homeostasis; the SIPA1 PDZ domain binds AQP2. Rrp1b or AQP2 binding inhibits the RapGAP activity of SIPA1. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This SIPA1-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged as beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta- strand F.

PDZ domain of SH3 and multiple ankyrin repeat domains protein 1 (SHANK1), SHANK2, SHANK3, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of SHANK1, SHANK2, SHANK3, and related domains. SHANK family proteins, SHANK1 (also known as somatostatin receptor-interacting protein, SSTR-interacting protein, SSTRIP), SHANK2 (also known as cortactin-binding protein 1, proline-rich synapse-associated protein 1), and SHANK3 (proline-rich synapse-associated protein 2) are synaptic scaffolding proteins which are highly enriched in the post-synaptic densities of excitatory synapses. They have been implicated in synaptic transmission, synapse formation, synaptic plasticity, and cytoskeletal remodeling, and are regulators of Cav1 calcium current and CREB target expression. Many protein ligands have been identified for the Shank PDZ domain, such as GKAP (also known as SAPAP), betaPIX (a guanine nucleotide exchange factor used by Rho GTPase family members Rac1 and Cdc42), alpha-latrotoxin, neuroligin, group I metabotropic glutamate receptors (mGluRs), and L-type calcium channels.

PDZ domain 1 of delphilin (L-delphilin isoform), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of delphilin (also known as glutamate receptor, ionotropic, delta 2-interacting protein 1, L-delphilin). Delphilin, a postsynaptic protein which is selectively expressed at cerebellar Purkinje cells, links the glutamate receptor delta 2 subunit (GluRdelta2) with the actin cytoskeleton and various signaling molecules. Two alternatively spliced isoforms of delphilin have been characterized: L-delphilin has two PDZ domains, PDZ1 and PDZ2, and S-delphilin has a single PDZ domain (PDZ2). These two isoforms are differently palmitoylated and may be involved in controlling GluRdelta2 signaling in Purkinje cells. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

PDZ domain of sorting nexin-27 (SNX27), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of SNX27, and related domains. SNX27 is involved in retrograde transport from endosome to plasma membrane. The PDZ domain of SNX27 links cargo identification to retromer-mediated transport. SNX27 binds to the retromer complex (vacuolar protein sorting 26(VPS26)-VPS29-VPS35), via its PDZ domain binding to VPS26. The SNX27 PDZ domain also binds to cargo including the G-protein-coupled receptors (GPCRs): beta2-adrenergic receptor (beta2AR), beta1AR, parathyroid hormone receptor (PTHR), alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs), NMDA receptors, 5-hydroxytryptamine 4a receptors, frizzled receptors, and somatostatin receptor subtype 5 (SSTR5). Additional binding partners of the SNX27 PDZ domain include G protein-gated inwardly rectifying potassium (Kir3) channels, angiotensin-converting enzyme 2 (ACE2), and PTEN (phosphatase and tensin homolog deleted on chromosome 10); PTEN binding to SNX27 prevents SNX27's association with the retromer complex. SNX27 has been reported to be a host factor needed for efficient entry of an engineered SARS-CoV-2 variant, the spike protein of which contains a deletion at the S1/S2 subunit cleavage site; the PDZ domain of SNX27 binds angiotensin-converting enzyme 2 (ACE2), and may be involved in recycling ACE2 to the plasma membrane, thereby promoting viral entry. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This SNX27-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

PDZ domain of ARHGEF11, ARHGEF12, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of ARHGEF11, ARHGEF12, and related domains. This subfamily includes the GEFs (guanine exchange factors) ARHGEF11 (Rho guanine nucleotide exchange factor 11, known as PDZ-RhoGEF) and ARHGEF12 (Rho guanine nucleotide exchange factor 12, also known as leukemia-associated RhoGEF). GEFs activate Rho GTPases by promoting GTP binding. ARHGEF11/12 are regulators of G protein signaling (RGS) domain-containing GEFs; the RGS domain mediates their binding to and activation of Galpha (and Gq also in the case of ARHGEF12), in response to G-protein coupled receptor activation. ARHGEF11 and 12 are involved in serum-signaling, and regulate Yes-Associated Protein (YAP1)-dependent transcription. The ARHGEF12 PDZ domain binds plexin-B1 and the receptor tyrosine kinase insulin-like growth factor receptor (IGF-R1) beta-subunit. ARHGEF12 also interacts with glutamate receptor delta-1(GluD1), a postsynaptic organizer of inhibitory synapses in cortical pyramidal neurons. The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This ARHGEF11-12-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.
