Summary: Predicted to enable protein homodimerization activity and spermidine synthase activity. Acts upstream of or within cellular response to leukemia inhibitory factor. Predicted to be active in cytosol. Is expressed in several structures, including alimentary system; brain; ear; genitourinary system; and integumental system. Orthologous to human SRM (spermidine synthase). [provided by Alliance of Genome Resources, Dec 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.
