The minor histocompatibility antigen 60 (H60a) is expressed in BALB/C and 129/Sv but not in C57BL/6 strains of mice. We recently found that IFNγ down-regulates H60a, but the mechanism of regulation is not known. To better understand the regulation of H60a, we examined the genomic locus of H60a in 129/Sv and C57BL/6 strains. We found that the upstream regulatory region of H60a was present and functional in both strains. Interestingly, IFNγ can down-regulate H60a transcripts in cell lines from 129/Sv but not C57BL/6 strains of mice, suggesting that IFNγ-dependent regulation of H60a proceeds through cis elements other than the conserved promoter region. We determined that the regulation of H60a by IFNγ proceeds through the 3'UTR of H60a, which is present in 129/Sv, but not C57BL/6 cells. We also found that the H60a 3'UTR and microRNAs can contribute to the level of constitutive expression of H60a in tumor cell lines. We conclude that in 129/Sv strain mice, H60a can be regulated by its 3'UTR through IFNγ and unknown microRNAs. Since H60a mediates NK cell target recognition, our studies identify a cis element that can regulate virus and tumor surveillance.

Commercial organization which provides reagents and services for molecular biology research. Its services include clone collections, microRNA solutions, genome editing, qPCR products, and fluorescent labeling and detection.
View all literature mentionsWeb search tool to find regions of similarity between biological sequences. Program compares nucleotide or protein sequences to sequence databases and calculates statistical significance. Used for identifying homologous sequences.
View all literature mentionsIt is the distribution arm of their academic laboratory. They operate on a cost-recovery mechanism in order to make the resources generated in their laboratory available to the academic scientific community. While clones and screening services are widely available, library arrays are primarily available to researchers with a scientific need to analyze most clones in the library. This site contains information on currently available BAC and PAC genomic DNA libraries, BAC Clones, PAC Clones, Fosmid Clones, cDNA collections, high-density colony hybridization filters, and BAC and PAC cloning vectors. Protocols used in our laboratory for the hybridization-based screening of colony filters, purification of BAC and PAC DNA, and end-sequencing methodologies, are also provided. BPRC does not list clones, for two reasons: 1)most clones have not been characterized and lack specific data. 2)all clones are part of libraries and all clones from a particular library share common characteristics. Hence, to find out if BPRC has a particular clone, one needs either use Automatic Clone Validation or else find out if the clone is compatible with the range of clone names for a corresponding clone library. Typically (although not always), clone names are derived from the library name. BPRC uses the NCBI-recommended clone nomenclature & library nomenclature. Most arrayed libraries are available in frozen microtiter dish format to academic and non-academic users provided that there is a scientific need for complete-library access. (for instance to annotate, modify or analyze all BAC clones as part of a genome project).
