Hello, Thank you for pointing this out - one of the data points was still in a 0-based half open format (our standard). We have corrected the data point to be 1-based and reformatted the section to make this data more clear. As you noticed, there is strong similarity upstream of the PAR2 region, but these bases are not a part of the official PAR regions as reported by NCBI.
We appreciate the feedback and especially your patience while we worked to make the correction!
