Enables guanyl-nucleotide exchange factor activity and inositol 1,4,5 trisphosphate binding activity. Predicted to be involved in negative regulation of dendrite development. Predicted to act upstream of or within regulation of cell adhesion. Located in bicellular tight junction. Is active in glutamatergic synapse and postsynapse. Is expressed in brain and spinal cord. Orthologous to human CYTH2 (cytohesin 2).
