Predicted to enable several functions, including guanylate cyclase inhibitor activity; protein C-terminus binding activity; and ubiquitin-specific protease binding activity. Predicted to be involved in negative regulation of cGMP-mediated signaling and protein localization to plasma membrane. Located in several cellular components, including apical part of cell; brush border; and cytoplasm. Orthologous to human PDZD3 (PDZ domain containing 3).
