    Summary
    Predicted to enable serine-type endopeptidase inhibitor activity. Involved in cellular response to BMP stimulus and negative regulation of neural precursor cell proliferation. Predicted to be located in cytoplasm. Human ortholog(s) of this gene implicated in congenital secretory sodium diarrhea 3. Orthologous to human SPINT2 (serine peptidase inhibitor, Kunitz type 2).

    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.
