Project Name and Description
We elected to clone the T1R3 gene to produce mammalian sweet taste receptors from humans. The gene sequence was acquired from the NCBI database of which the source is a patent. The accession number for the gene is: DJ044031. The T1R3 gene contains 2553 base pairs and 0 introns. DNA will be extracted from my mouth. We will amplify the gene with PCR using flanking primers that have been designed specifically for this gene sequence. We chose original sets of gene-specific primers of 17 base pairs each that minimized potential formation of secondary structures within the primers themselves. Two sets of primers will be used: the gene-specific set and a set that contains the gene-specific sequence and BioBrick compatible restriction sites. We have elected to first try to amplify the gene using the BioBrick compatible primers into a vector containing our promoter. Our promoter will be chosen from a short list chosen from the BioBricks registry website. If this fails, we will utilize the gene specific primers and then insert our amplified gene into a T-vector. The plasmid vector possessing our clone will be transferred to E. Coli and allowed to mature. The mature E. coli colony is expected to produce the T1R3 taste receptor molecule. All the while we will be performing a simultaneous cloning process using the miraculin gene from the BioBrick library. We will isolate the miraculin protein product and combine the miraculin protein with the T1R3 receptor. As of yet, we have not found the native gel conditions for this receptor which are required to observe the functionality of the T1R3 protein combined with a protein molecule. If said native gel conditions are located, we will perform an SDS-PAGE analysis of the miraculin protein, the T1R3 receptor, and a combination of the two which should contain bound T1R3-miraculin molecules.
