Lee JW. TM4SF5-mediated protein-protein networks and tumorigenic roles. BMB Rep. 2014;.
Transmembrane 4 L six family member 5 (TM4SF5), as a membrane glycoprotein with 4 transmembrane domains, is similar to the tetraspanins in terms of membrane topology and plays important roles in tumorigenesis and tumor metastasis. Especially, TM4SF5 appears to form a massive protein-protein complex consisting of diverse membrane proteins and/or receptors in addition to cytosolic signaling molecules to regulate their signaling activities during the pathological processes. It is shown to interact with integrins 2, 5, and 1, EGFR, IL6R, CD151, focal adhesion kinase (FAK), and c-Src, so that this review has focuses on the significance of the interactions with regards to TM4SF5-positive tumorigenesis and metastasis.
