Predicted to enable long-chain fatty acid binding activity; protein tyrosine kinase binding activity; and ubiquitin-like protein ligase binding activity. Involved in negative regulation of protein ubiquitination and postsynapse to nucleus signaling pathway. Located in neuron projection; nucleus; and postsynaptic density. Is active in glutamatergic synapse and postsynaptic density, intracellular component. Orthologous to human PRR7 (proline rich 7, synaptic). [provided by Alliance of Genome Resources, Apr 2022]
