Summary: Enables identical protein binding activity; integrin binding activity; and sialic acid binding activity. Involved in maintenance of synapse structure and regulation of synapse assembly. Acts upstream of or within several processes, including cell-cell adhesion mediated by integrin; heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; and homophilic cell adhesion via plasma membrane adhesion molecules. Located in external side of plasma membrane and terminal bouton. Is active in several cellular components, including GABA-ergic synapse; Schaffer collateral - CA1 synapse; and presynaptic membrane. Is expressed in several structures, including alimentary system; nervous system; respiratory system; sensory organ; and urinary system. Used to study MASA syndrome. Human ortholog(s) of this gene implicated in MASA syndrome; hydrocephalus; ovarian carcinoma; pancreatic cancer; and schizophrenia. Orthologous to human L1CAM (L1 cell adhesion molecule).

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.
