    • The initial isolate of SHP was one of several clones obtained from an appropriate mouse liver cDNA library (4) through use of the interaction trap (2) with a LexA fusion to the hinge and ligand-binding and dimerization domains of mCAR as a bait. Interaction-trap screening was as described for isolation of proteins that interact with TR (6) and RXR (4). mCAR is a close murine relative of the orphan MB67 (10) that is also an apparently constitutive transactivator of a subset of RAREs (H.-S. Choi, D. Simha, D. D. Moore, unpublished data). Twelve independent murine SHP clones were isolated from two different mouse liver cDNA libraries through the use of conventional screening. The 5′ ends of 10 of the 12 clones fall within a 32-bp segment upstream of the first methionine codon, which includes a good match to the consensus for translation initiation. One additional clone starts within the coding region, and the other contains 16 bp that diverge from those of the majority class upstream of the eighth amino acid. Despite extensive screening, no clones were isolated that corresponded to a larger SHP transcript present at very low levels in liver. It remains unclear whether this minor species represents a larger mRNA or a nuclear precursor not present in the cytoplasmic RNA used to make the libraries. One human cDNA clone was isolated by screening a human liver library with a fragment of the mouse clone as a probe. The human clone begins at the second position of the putative initiator methionine codon and includes a 318-bp intron with apparent 5′ and 3′ splice sites between amino acids 178 and 179 The murine (L76567) and human (L76571) SHP cDNA sequences have been deposited in GenBank.

    • -6 M ligand (all-trans-retinoic acid, 9-cis-retinoic acid, or triiodothyronine) increased β-galactosidase expression in cells coexpressing B42-SHP and LexA-RAR (73 to 104 U), B42-SHP and LexA-RXR (87 to 96 U), and B42-SHP and LexA-TR (1 to 89 U). Cells coexpressing LexA alone with B42-SHP expressed 1 U of β-galactosidase.

    • 35S-labeled proteins were precleared by incubation with GST alone bound to glutathione-Sepharose-4B beads. After centrifugation, the supernatant was incubated with GST-SHP or GST protein. Specifically bound proteins were eluted from beads with 40 mM reduced glutathione in 50 mM tris (pH 8.0).
