Cell localization:Membrane, Single-pass type I membrane protein..The protein encoded by this gene may play a role in the attachment of stem cells to the bone marrow extracellµLar matrix or to stromal cells. This single-pass membrane protein is highly glycosylated and phosphorylated by protein kinase C. Two transcript variants encoding different isoforms have been found for this gene.
