This entry represents the C-terminal domain of the ERM family of proteins which consists of three closely-related proteins, ezrin, radixin and moesin [1]. These proteins link actin filaments of cell surface structures to the plasma membrane, using a C-terminal F-actin binding segment and an N-terminal FERM domain (Pfam:PF00373), a common membrane binding module [1,2]. Ezrin was first identified as a constituent of microvilli [3], radixin as a barbed, end-capping actin-modulating protein from isolated junctional fractions [4] and moesin as a heparin binding protein [5]. A tumour suppressor molecule responsible for neurofibromatosis type 2 (NF2) is highly similar to ERM proteins and has been designated merlin (moesin-ezrin-radixin-like protein). This entry represents the C-terminal actin-binding tail domain [6,7]. This entry also includes Ermin proteins, oligodendrocyte-specific proteins associated with the cytoskeleton whose C-terminal domain is similar to that in ERM family [8].	Domain
