Summary: Enables N-acylneuraminate-9-phosphate synthase activity. Predicted to be involved in N-acetylneuraminate biosynthetic process and glycosylation. Is active in cytosol. Is expressed in several structures, including alimentary system; early conceptus; sensory organ; skeleton; and tarsus. Human ortholog(s) of this gene implicated in spondyloepimetaphyseal dysplasia, Genevieve-type. Orthologous to human NANS (N-acetylneuraminate synthase).

What's a GeneRIF?

Intracellular localization of this enzyme is regulated not only due to the nuclear localization signal but also two nuclear export signals.

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.
