| abstractText | A new murine member of the interferon (IFN)-inducible guanylate-binding protein (GBP) family was cloned in a search for glucocorticoid-attenuated response genes induced in the lung during endotoxemia. The full-length MuGBP-5 cDNA encodes a 590 amino acid residue protein with GTP binding motifs identical to those in human GBP-1 (HuGBP-1) and a similar isoprenylation sequence at the C-terminus. An alternatively spliced form of MuGBP-5 that lacks the second GTP binding motif and differs at the C-terminus was also identified. The MuGBP-5 gene is located on chromosome 3, near MuGBP-3 and MuGBP-2, and has a genomic organization similar to other GBP genes. To facilitate the evaluation of GBP family message expression, we constructed RNase protection assay probes for MuGBP-1, MuGBP-2, MuGBP-3, MuGBP-4/Mag-2 (macrophage activation gene-2), and MuGBP-5 and validated their use in Swiss Webster, BALB/c, and C57BL/6 mice. In BALB/c mice, all five MuGBPs were induced in multiple organs during endotoxemia, and all had a similar pattern of expression in different tissues. With minor quantitative differences, the MuGBPs also had similar patterns of response to IFN-gamma, lipopolysaccharide (LPS), interleukin-1beta (IL-1beta), and tumor necrosis factor-alpha (TNF-alpha) in RAW 264.7 and Swiss 3T3 cells. The coordinate expression of the MuGBPs suggests that they share common mechanisms of regulation. |
