Summary: Predicted to enable spermine synthase activity. Acts upstream of or within spermine metabolic process. Is expressed in several structures, including central nervous system; ganglia; limb; respiratory system; and tooth.

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.
