Antibody immunologically reactive with serine protease EOS

   
   

Here we describe the molecular identification of a cDNA encoding a novel serine protease we have termed protease EOS. The deduced amino acid sequence, and it alignment with other well-characterized serine proteases indicates that it is a member of the S1 serine protease family. We have found that the protease EOS mRNA is expressed in platelets and leukocytes and more specifically eosinophils. Although this protease is abundantly expressed in ovary, retina and stomach, where it may perform important functions, its expression in platelets and certain cells of the immune system suggests that it may play roles in thrombosis and in the immune process. Enzymatically active protease EOS is amenable to further biochemical analyses for the identification of physiological substrates and specific modulators.

Aqui nós descrevemos a identificação molecular de um DNA que codifica um protease que do serine da novela nós denominamos o EOS do protease. A seqüência deduzida do amino-ácido, e alinhamento com outros proteases bem-caracterizados do serine indicam que é um membro da família do protease do serine S1. Nós encontramos que o mRNA do EOS do protease está expressado nos platelets e os leukocytes e mais especificamente os eosinophils. Embora este protease seja expressado abundante no ovary, no retina e no estômago, onde pode executar funções importantes, sua expressão nos platelets e em determinadas pilhas do sistema imune sugere que pode jogar papéis no thrombosis e no processo imune. O EOS enzymatically ativo do protease é amenable a umas análises biochemical mais adicionais para a identificação de carcaças physiological e de moduladores específicos.
