    Summary
    Predicted to enable molecular adaptor activity. Predicted to be involved in clathrin-dependent synaptic vesicle endocytosis and positive regulation of dendrite extension. Predicted to be located in centrosome. Predicted to be active in cytoplasm; intracellular vesicle; and presynaptic membrane. Is expressed in several structures, including endocrine gland; hemolymphoid system; ileum; male reproductive gland or organ; and nervous system. Used to study nephrotic syndrome. Orthologous to human ITSN2 (intersectin 2). [provided by Alliance of Genome Resources, Nov 2024]

    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.
