Complexos de reparo mismatch: mecanismos e funções
Palavras-chave:
Reparo de DNA Mismatch. MutL. MutS. MSH2.Resumo
As proteínas do Reparo de DNA Mismatch (MMR) são encontradas em diversos mecanismos importantes de funções celulares. A principal função dessas proteínas está relacionada ao reparo pós replicacional do
DNA, corrigindo as bases incorporadas incorretamente ao genoma devido ao erro de replicação. A perda das
funções das proteínas MMR é geralmente aumentada devido a mutações espontâneas em organismos, que vão
desde bactérias a humanos. As mutações nos genes MMR causam câncer colorretal hereditário não-poliposo,
e, a perda das funções dos genes MMR está associada com uma significativa fração de cânceres esporádicos.
Esta revisão busca resumir os principais mecanismos moleculares das funções protéicas dos MMR. O conhecimento acerca do mecanismo de reparo MMR está em processo de crescimento ao longo dos anos, embora a complexidade de suas vias de sinalização, ainda, permanece pouco conhecida. O entendimento desses
mecanismos, portanto, faz-se crucial para maior suporte no desenvolvimento de novos alvos terapêuticos para
doenças relacionadas a essa via de reparo.
