Summary: Predicted to enable growth factor activity. Acts upstream of with a positive effect on positive regulation of mitotic cell cycle. Acts upstream of or within several processes, including cardiac muscle tissue regeneration; neural tube formation; and sensory epithelium regeneration. Located in Golgi apparatus. Is expressed in several structures, including heart; nervous system; neural tube; neuroectoderm; and paraxial mesoderm. Human ortholog(s) of this gene implicated in brain ischemia. Orthologous to human MDK (midkine). [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.
