Banda 4.1 o Proteína 4.1R o Sinaprina. en un miembro de la superfamilia de proteínas 4.1. Es una de las proteínas que participa en la unión del citoesqueleto a la membrana plasmática en los eritrocitos. Posee un dominio FERM con el que interacciona con glucoproteínas de la membrana plasmática, un dominio SABD que permite su interacción con la actina y con la espectrina y un dominio CTD en la zona del carboxi-terminal. Es expresada a partir del gen EPB41 localizado en el cromosoma 1 (1p36.2-34) con una extensión de 200kpb.
