Ver/Editar Humano

Cytovillin também conhecido como ezrin ou villin-2 é uma proteína que em humanos é codificada pelo gene EZR.[2]

Estrutura

O terminal N de cytovillin contém um domínio FERM[3] que é subdividido em três subdomínios. O terminal C contém um domínio ERM.[4]

Função

A proteína periférica[5] citoplasmática codificada por esse gene pode ser fosforilada pela proteína-tirosina-quinase em microvilos e é um membro da família de proteínas ERM.[6]

O VIL2 demonstrou interagir com:

  • CD43,[7]
  • FASLG,[8][9]
  • ICAM-1,[10]
  • ICAM2,[10]
  • ICAM3,[10][11]
