Nepn{Cherry} mouse ESC line A mouse ESC line in which the targeted gene, Nephrocan (NCBI Gene ID: 66650), has been modified (allele type: Global Null) to (MGI ID: Neph(mCherry)). This ES cell line was made by gene targeting and was designed to express red fluorescent protein (mCherry) from the Nepn promoter thereby disrupting the expression of Nepn. The FP coding sequence was inserted dowstream of the Nepn start codon, in front of the Nepn first exon. This cell line is used to study the function and expression of Nepn. Person: Mark A.
