Summary: 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Description

Transcript Variant: This variant (3) differs in the 5' UTR, 3' UTR and coding region, compared to variant 1. These differences cause translation initiation at a downstream AUG and result in an isoform (3) with a shorter N-terminus compared to isoform 1. Variants 3 and 6 both encode the same isoform (3).
