Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables PDZ domain binding activity; identical protein binding activity; and ubiquitin-protein transferase activity. Involved in synapse maturation. Acts upstream of or within ubiquitin-dependent protein catabolic process. Located in cytoplasm. Is active in hippocampal mossy fiber to CA3 synapse and postsynapse. Is expressed in several structures, including brain; genitourinary system; liver; nasal epithelium; and spleen. Orthologous to human LNX1 (ligand of numb-protein X 1).
