As a component of the minor spliceosome, involved in the splicing of U12-type introns in pre-mRNAs (Probable). Involved in the cytoskeletal anchoring of DLG4 in excitatory synapses (By similarity).
Subcellular locations: Cytoplasm, Synapse, Cell projection, Dendritic spine
Colocalizes with DLG4 in asymmetric synapses.
