rhodopsin siganl peptide +IL-8 receptor type alpha (CXCR1)
rhodopsin siganl peptide +IL-8 receptor type alpha (CXCR1)
Usage and Biology
The rhodopsin-CXCR1 sequence is a combination of bovine rhodopsin signal peptide (BBa_K1728020) and CXCR1 with optimized sequence(BBa_K1728021)
Western blot analysis of Rho-CXCR1 expression
https://static.igem.org/mediawiki/2015/4/4a/CGU_Taiwan_r08.tif
The galactose induction of CXCR1 expression was performed as described in protocol. We collect yeast samples at different induction time. Protein extracted from the yeast whole-cell extract was separated on SDS-PAGE and finally detected by anti-CXCR1 antibody.
Effect of IL-8 treatment in engineered yeast with Rho-CXCR1 expression
Plasmid p426GAL-CXCR1 was transformed into engineered yeast, and CXCR1 was induced by 2 % galactose overnight. At first, we could not see GFP production. In order to exclude the possibility that cell wall blocks the binding between CXCR1 and IL-8, yeast cells were digested with zymolyase to remove cell wall and became spheroplasts. After that, we add 1 μM IL-8 to stimulate GPCR-mediated pathway, we observed GFP after IL-8 treatment for 8 hours. The negative control is the same yeast strain without IL-8 treatment.
