Enables 15-hydroxyprostaglandin dehydrogenase (NAD+) activity and identical protein binding activity. Involved in several processes, including positive regulation of vascular associated smooth muscle cell proliferation; prostaglandin metabolic process; and thrombin-activated receptor signaling pathway. Located in cytoplasm and extracellular space. Used to study carcinoma. Biomarker of peptic ulcer disease. Human ortholog(s) of this gene implicated in colon carcinoma and primary hypertrophic osteoarthropathy. Orthologous to human HPGD (15-hydroxyprostaglandin dehydrogenase).
