Abstract:
1. A CSR::T1R chimeric protein able to bind to at least one of an umami modulator or an umami tastant, wherein said protein comprises one or more CSR::T1R polypeptides selected from: a CSR::T1R1 polypeptide comprising an amino acid sequence with a sequence identity of at least 90% to SEQ ID NO:2 and a CSR::T1R3 polypeptide comprising an amino acid sequence with a sequence identity of at least 90% to SEQ ID NO:4 and wherein said protein is selected from the group consisting of a CSR::T1R1 homomeric chimeric protein, a CSR::T1R1/CSR::T1R3 heterodimeric chimeric protein, a CSR::T1R1/T1R3 heterodimeric chimeric protein, and a T1R1/CSR::T1R3 heterodimeric chimeric protein.
