The functions of members of the large family of transcriptional repressors, the KRAB domain zinc finger proteins, are not well described. We have identified a new member of this family, Zfp157, as a downstream target of the transcription factor Stat6 in mammary gland. Using a gene‐trap approach, we have generated mice harboring a Zfp157‐LacZ reporter gene. We have characterized the expression of this reporter during mouse embryogenesis and show that it is expressed in the epiblast and subsequently in a number of embryonic tissues including brain, ovary, intestine, kidney, lung, mammary gland, and hair follicle. In the adult, Zfp157 continues to be expressed in a wide range of tissues while specific patterns of reporter gene expression are apparent in the mammary gland, primarily in the basal epithelial cells of ducts and in the sebaceous glands of hair follicles. These data lay the foundation for further work on the function of Zfp157. genesis 51:179–186, 2013. © 2013 Wiley Periodicals, Inc.
