Enables PDZ domain binding activity and microtubule binding activity. Involved in several processes, including cytoplasmic microtubule organization; protein localization to microtubule; and regulation of postsynaptic density protein 95 clustering. Located in dendrite; neuronal cell body; and postsynaptic density. Orthologous to human CRIPT (CXXC repeat containing interactor of PDZ3 domain). [provided by Alliance of Genome Resources, Apr 2022]
