Seam cell marker

Recently I am making transgenic animals that express genes in the seam cell. I found scm (seam cell marker) gene was commonly used, but I have difficulties in finding detail info.
I was wondering if anyone can provide the full sequence, primer info for cloning and possibly the plasmid.

I don’t know the sequence of the scm promoter, but Mullaney et al. (Cell Metabolism, 2010) used wrt-2 and grd-10 promoters. These were previously characterized as seam cell-specific by Aspock et al. (1999). I believe that Kaveh Ashrafi’s lab has entry clones for these plasmids and the primers used to clone them are on Marc Vidal’s promoterome website.
