ROSA26 is a locus used for constitutive, ubiquitous gene expression in
mice.[1] It was first isolated in 1991[2] by the group of Philippe Soriano in a gene-trap mutagenesis screen of
embryonic stem cells (ESCs). Over 800
knock-in lines have been created based on the ROSA26 locus according to the
MGI database.[3] The human
homolog of the ROSA26 locus has been identified.[4] ROSA stands for Reverse Orientation Splice Acceptor, named after the
lentivirus genetrap vector.[5]
