Summary: Enables protein sequestering activity. Involved in several processes, including negative regulation of hippo signaling; positive regulation of imaginal disc growth; and protein localization to centrosome. Located in adherens junction and apical cortex. Colocalizes with apical part of cell and pericentriolar material. Is expressed in interommatidial cell. Orthologous to several human genes including WTIP (WT1 interacting protein). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

The study observations establish Jub as a reporter of tension experienced at adherens junctions, and identify distinct types of tension-dependent and tension-independent junctional complexes.
Title: Organization and function of tension-dependent complexes at adherens junctions.
our findings indicate that a-Cat acts through multiple mechanisms to control tissue growth, including regulation of AJ stability, mechanosensitive Ajuba recruitment, and dynamic direct F-actin interactions.
Title: Role of α-Catenin and its mechanosensing properties in regulating Hippo/YAP-dependent tissue growth.
These results demonstrate that Ajuba plays an essential role in regulating cell adhesion in response to mechanical forces generated by epithelial morphogenesis.
Title: The force-sensitive protein Ajuba regulates cell adhesion during epithelial morphogenesis.
Study reports that increasing tension within the cytoskeleton increases Drosophila wing growth, whereas decreasing cytoskeletal tension decreases wing growth; Jub associates with alpha-catenin and that its localization to adherens junctions and association with alpha-catenin are promoted by cytoskeletal tension. Jub recruits Warts to junctions in a tension-dependent manner.
Title: Cytoskeletal tension inhibits Hippo signaling through an Ajuba-Warts complex.
A molecular mechanism linking JNK activity to Yki regulation. JNK can promote YAP activity in mammalian cells.
Title: Ajuba family proteins link JNK to Hippo signaling.
Mutation in jub leads to centrosome separation defects and aberrant mitotic spindles.
Title: Drosophila Ajuba is not an Aurora-A activator but is required to maintain Aurora-A at the centrosome.
