Abstract

PLATAFORMA GENÉTICA PARA SUPEREXPRESSÃO HETERÓLOGA ASSOCIADA À SELEÇÃO DE CÉLULAS ALTAMENTE PRODUTORAS DE PROTEÍNAS. A presente invenção descreve i) a construção de vetores de integração para superexpressão heteróloga associados a um sistema de seleção de células e monitoramento em tempo real da produtividade pela co-expressão de proteínas repórteres, ii) a seleção de células altamente secretoras da proteína de interesse pela marcação com sondas fluorescentes específicas para o retículo endoplasmático (RE), iii) construção de uma linhagem geneticamente modificada de células CHO para expressão condicional de proteínas de interesse sobre o controle de tetraciclina/doxiciclina (sistema TetON), iv) desenvolvimento de um gene sintético contendo as formas ativas das proteínas Atf6 e Xbp1 fusionadas em um único polipeptídeo e de linhagens de células CHO expressando a fusão Atf6-Xbp1 sob o controle (ou não) de tetraciclina, v) super expressão e alta produtividade de proteínas recombinantes pela co-expressão regulada de Atf6-Xbp1.
