Function

Merlin (Mer) or Moesin-exrin-radixin-like protein is a unique tumor suppressor that inhibits mitogenic signaling at the membrane-cytoskeleton interface^[1]. The FERM domain of Mer regulates cell proliferation in response to adhesive signaling^[2].

Disease

Neurofibromatosis type 2, characterized by tumors of the nervous system, is the result of loss of the NF2 gene which encodes Mer^[3].

Structural highlights

The binding of Mer FERM domain to the C-terminal of HIV-1 Vpr-binding protein results in the inhibition of Mer-mediated suppression of tumorigenesis. The interactions between the proteins are formed by the α-helix and a β-sheet of Mer and a mostly β-sheet of HIV-1 Vpr-binding protein^[4].
