Background: MEGF9

MEGF9 (Multiple EGF‑like domains protein 9; also EGF‑like protein 5) is a novel transmembrane glycoprotein with multiple EGF-like repeats. It is predominantly expressed in the developing and adult central nervous system and peripheral nervous system. Immunohistochemical studies showed that MEGF9 is expressed in Purkinje cells of the cerebellum and in glial cells of the peripheral nervous system. In non-neuronal tissues, MEGF9 is expressed in epidermal layer of skin, papillae of the tongue and epithelium of the gastrointestinal tract. MEGF9 is suggested to participate in cell motility, and its absence correlates with tumor cell migration.  Mature human MEGF9 is 572 amino acids (aa) in length. It is a single span type I transmembrane protein that contains a 484 aa extracellular domain (ECD). The extracellular region possesses a lengthy Pro‑rich region (aa 55‑200). N-terminal region of MEGF9 includes several potential O-glycosylation sites followed by five EGF-like domains which are highly homologous to the short arms of laminins. Following one single pass transmembrane domain, a highly conserved short intracellular domain with potential phosphorylation sites is present (1, 2). Within the ECD, human MEGF9 shares 75% aa sequence identity with mouse and rat MEGF9.
