    Summary
    Contributes to serine C-palmitoyltransferase activity. Acts upstream of or within ceramide biosynthetic process; endoplasmic reticulum organization; and regulation of serine C-palmitoyltransferase activity. Part of serine palmitoyltransferase complex. Is expressed in central nervous system; eye; genitourinary system; and gut. Orthologous to human SPTSSB (serine palmitoyltransferase small subunit B).

    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.
