Sox transcription factors play key regulatory roles throughout development, binding DNA through a consensus (A/T)(A/T)CAA(A/T)G sequence. Although many different Sox proteins bind to this sequence, it has been observed that gene regulatory elements are commonly responsive to only a small subset of the entire family, implying that regulatory mechanisms exist to permit selective DNA binding and/o...

Sox-18 is a member of the Sox multi-gene family (Sry-related HMG-box gene). We have bacterially expressed this 378 amino acid protein and demonstrated sequence-specific binding to the Sox DNA-binding motif AACAAAG. A distinct 95 amino acid activation domain was mapped in Sox-18 using GAL4-Sox-18 fusions (amino acids 160-225). Furthermore, Sox-18 was capable of trans-activating gene expression t...

This study examines the impact of the Sarbanes-Oxley Act (SOX) on bondholders, a significant investor group that has not been previously considered in the SOX literature. We find that bond values decline around the announcement of events leading up to the passage of SOX, consistent with market participants expecting SOX to impose net costs on bondholders. We further find that the decline in bon...

Members of the Sox gene family of transcription factors are defined by the presence of an 80 amino acid homology domain, the High Mobility Group (HMG) box. Here we report the cloning and initial analysis of murine Sox-13 . The 984 amino acids Sox-13 protein contains a single HMG box, a leucine zipper motif and a glutamine-rich stretch. These characteristics are shared with another member of the...

The developmental transcription factor SOX-4 has been shown to be highly and differentially overexpressed in primary small cell lung carcinomas (SCLC). To examine the potential of SOX-4 for broad use as a lung cancer vaccine, we have evaluated the expression of SOX-4 in a panel of primary adenocarcinoma, squamous, and large cell tumor samples as well as in a panel of established small cell and ...
