Enables ephrin receptor binding activity and protein tyrosine kinase activity. Involved in phosphorylation and positive regulation of apoptotic process. Located in dendrite; neuronal cell body; and postsynaptic membrane. Is active in several cellular components, including Schaffer collateral - CA1 synapse; glutamatergic synapse; and hippocampal mossy fiber to CA3 synapse. Is integral component of postsynaptic density membrane. Orthologous to human EPHA7 (EPH receptor A7). [provided by Alliance of Genome Resources, Apr 2022]
