Predicted to enable cAMP response element binding protein binding activity. Involved in positive regulation of dendrite development; positive regulation of long-term synaptic potentiation; and postsynapse to nucleus signaling pathway. Located in cytoplasm; neuronal cell body; and nucleus. Is active in glutamatergic synapse and postsynaptic density. Colocalizes with dendrite and synapse. Biomarker of middle cerebral artery infarction. Orthologous to human CRTC1 (CREB regulated transcription coactivator 1). [provided by Alliance of Genome Resources, Apr 2022]
