Background: Olfactomedin-4/OLFM4

Olfactomedin-4 (OLFM4), previously called GC-1 (G-CSF stimulated clone-1) is an approximately 64-72 kDa secreted glycoprotein that is a member of the Olfactomedin/Noelin family of protein (1-3). It is expressed in epithelial cells of the prostate, small intestine, colon, bone marrow, and in several cancers (4-7), and is up-regulated in epithelial cells during inflammation (8). Mature OLFM4 is a 490 amino acid (aa) protein that is secreted mainly in a polymeric form which is held together by disulfide bonds and carbohydrate interactions (2). Mature human OLFM4 shares 71% aa sequence identity with mature mouse and rat OLFM4. Olfactomedin-4 (OLFM4) interacts with cell surface lectins and cadherins, which helps cell adhesion and cell spreading of NIH3T3 and 293T/17 cells (9). OLFM4 plays a critical role in regulating progression of prostate cancer and is also novel biomarker for triple-negative breast cancer (10-11).
