Olfactomedin-4 (OLFM4), an olfactomedin domain-containing protein, belongs to the olfactomedin-related protein family. OLFM4 is found in the cytoplasm, mitochondria, and membrane including, other subcellular compartments. It is a disulfide-bonded multimer with a signal peptide and six N-linked glycosylation motifs. OLFM4 has a coil-coil domain at the N-terminus and an olfactomedin domain at the C-terminus. Endogenous expression of the OLFM4 protein is seen in mature neutrophils and gastric and intestinal epithelial cells. It is expressed ubiquitously in intestinal crypts and is secreted extracellularly. OLFM4 gene is located on human chromosome 13q14.3.

생화학적/생리학적 작용
Olfactomedin 4 (OLFM4) has a role in tumor growth. OLFM4 has been identified as an anti-apoptotic factor and an extracellular matrix (ECM) glycoprotein.
Olfactomedin-4 (OLFM4) can mediate cell adhesion by binding to cadherins and lectins. It may play a role in the defense of the gastrointestinal mucosal surface. Overexpression of the OLFM4 mRNA is observed in gastric and colon cancer patients. In the human intestine, OLFM4 is considered a powerful marker for stem cells.
