Predicted to enable ephrin receptor binding activity. Involved in postsynapse to nucleus signaling pathway. Acts upstream of or within receptor localization to synapse. Is active in several cellular components, including hippocampal mossy fiber to CA3 synapse; postsynaptic density, intracellular component; and presynaptic cytosol. Orthologous to human ANKS1B (ankyrin repeat and sterile alpha motif domain containing 1B). [provided by Alliance of Genome Resources, Apr 2022]
