TM4SF4 (transmembrane 4 L6 family member 4), also known as IL-TMP (intestine and liver tetraspanin membrane protein) is a member of the L6 tetraspanin family of molecules. It is expressed at highest levels on non-proliferating villus-associated intestinal epithelia and periportal hepatocytes, with increased expression in hepatocellular carcinomas. It is thought to mediate proliferation and adhesion. Its molecular size is reported at approximately 21 kDa for the unglycosylated form and 25-40 kDa for various glycosylated forms. The 202 amino acid (aa) human TM4SF4 contains four transmembrane domains and two potential N-glycosylation sites. It shares 88% aa sequence identity with mouse and rat TM4SF4.
