Moesin（膜組織延伸棘蛋白）是ErM家族的成員，包括Ezrin和Rexin。erm蛋白在質膜和肌動蛋白細胞骨架之間起交聯作用。moesin定位于絲狀體和其他膜性突起，對細胞識別、信號傳導和細胞運動具有重要意義。[由RefSeq提供，2008年7月]
Moesin (for membrane-organizing extension spike protein) is a member of the ERM family which includes ezrin and radixin. ERM proteins appear to function as cross-linkers between plasma membranes and actin-based cytoskeletons. Moesin is localized to filopodia and other membranous protrusions that are important for cell-cell recognition and signaling and for cell movement. [provided by RefSeq, Jul 2008]
