However, the underlying molecular mechanism of transcription repression remains undefined. PHD finger, a specialized form of zinc finger, has been implicated in regulating chromatin organization or gene expression. Mutations of PHD domain are responsible for several diseases and in some cases lead to mislocalization of proteins. RSF, an isoform of HBXAP, has been shown to associate with hsnf2h and functions as a chromatin remodeling complex. In the present study, we investigate the biological functions of HBXAP and identify its associated proteins. We demonstrate that HBXAP represses TNF-Abstract (Chinese) 1 Abstract (English) 2 Introduction 4 Materials and Methods 7 Results 1.
