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 Rap guanine nucleotide exchange factor 2 and Rap guanine nucleotide exchange factor 6, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Rap guanine nucleotide exchange factor 2 (RapGEF2, also named RA-GEF-1, PDZ-GEF1, CNrasGEF and nRapGEP) and Rap guanine nucleotide exchange factor 6 (RapGEF6, also named RA-GEF-2 and PDZ-GEF2). RapGEF2 and RapGEF6 constitute a subfamily of guanine nucleotide exchange factors (GEFs) for RAP small GTPases that is characterized by the possession of the PDZ and Ras/Rap-associating domains. They activate Rap small GTPases, by catalyzing the release of GDP from the inactive GDP-bound forms, thereby accelerating GTP loading to yield the active GTP-bound forms. The PDZ domain of RapGEF6 (also known as PDZ-GEF2) binds junctional adhesion molecule A (JAM-A). 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.

HAUS augmin-like complex subunit 3; This domain is subunit three of the augmin complex found from Drosophila to humans. The HAUS-augmin complex is made up of eight subunits. The augmin complex interacts with gamma-TuRC, and attenuation of this interaction severely impairs spindle MT generation. Furthermore, we provide evidence that human augmin plays critical and non-redundant roles in the kinetochore-MT attachment and also central spindle formation during anaphase in human cells.The HAUS complex is required for mitotic spindle assembly and for maintenance of centrosome integrity.

PDZ domain 1 of harmonin isoforms a, b, and c, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of harmonin isoforms a, b, and c, and related domains. Harmonin (also known as Usher Type 1C, PDZ-73 and AIE-75) is a key organizer of the Usher (USH) protein interactome. USH syndrome is the leading cause of hereditary sensory deaf-blindness in humans; three clinically distinct types of USH have been identified, type 1 to 3. The gene encoding harmonin (USH1C) is the causative gene for the USH type 1C phenotype. There are at least 10 alternatively spliced isoforms of harmonin, which are divided into three subclasses (a, b, and c). All isoforms contain the first two PDZ domains and the first coiled-coil domain. The a and b isoforms all have a third PDZ domain. The different PDZ domains are responsible for interactions with all known Usher syndrome type 1 proteins, and most Usher syndrome type 2 proteins. 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 harmonin family PDZ1 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.
