PDZ (PSD-95/Discs large/ZO-1 homologous) domains promote protein-protein interactions that affect cell signaling, adhesion, protein scaffolding, and receptor and ion transporter functions. The encoded protein interacts with a large number of target proteins that play roles in signaling pathways; for example, it interacts with Rho A and glutaminase L and also acts as a negative regulator of the Wnt/beta-catenin signaling pathway. This protein was first identified as binding to the T-cell leukaemia virus (HTLV1) Tax oncoprotein. Overexpression of this gene has been implicated in altered cancer cell adhesion, migration and metastasis. The encoded protein also modulates the localization and density of inwardly rectifying potassium channel 2.3 (Kir2.3). To date, this protein has been shown to play a role in cell proliferation, development, stress response, and polarization. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

Binds CTNNB1 and may thereby act as an inhibitor of the Wnt signaling pathway. Competes with LIN7A for KCNJ4 binding, and thereby promotes KCNJ4 internalization. May play a role in the Rho signaling pathway. May play a role in activation of CDC42 by the viral protein HPV16 E6. {ECO:0000269|PubMed:10940294, ECO:0000269|PubMed:16855024, ECO:0000269|PubMed:21139582}. |PDZ| |negative regulation of protein localization to cell surface| |regulation of protein localization to cell surface| |Rho protein signal transduction| |beta-catenin binding| |activation of GTPase activity| |negative regulation of cellular protein localization| |fibrillar center| |protein C-terminus binding| |negative regulation of Wnt signaling pathway| |actin cytoskeleton| |Ras protein signal transduction| |small GTPase mediated signal transduction| |Wnt signaling pathway| |cell-cell signaling by wnt| |regulation of Wnt signaling pathway| |positive regulation of GTPase activity| |cell surface receptor signaling pathway involved in cell-cell signaling| |regulation of GTPase activity| |regulation of cellular protein localization| |negative regulation of cell population proliferation| |intracellular membrane-bounded organelle| |positive regulation of hydrolase activity| |regulation of cellular localization| |regulation of protein localization| |cell-cell signaling| |negative regulation of signal transduction| |regulation of hydrolase activity| |negative regulation of cell communication| |negative regulation of signaling| |positive regulation of catalytic activity| |regulation of cell population proliferation| |negative regulation of response to stimulus| |intracellular signal transduction| |positive regulation of molecular function| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp176|Apcin 50 to 100μM on day4 R04 exp176]]|-1.94| |[[:results:exp311|2-Methoxyestradiol 0.55 to 0.75μM on day4 R07 exp311]]|1.8| |[[:results:exp135|MS023 7μM R03 exp135]]|1.93| |[[:results:exp392|PT-1 25μM R07 exp392]]|2.06| No correlation found to any other genes in chemogenomics.
