Figure 3. Model of three distinct transcriptional repression mechanisms for SHP.
SHP represses nuclear receptor (NR) or transcription factor (TF) mediated transactivation by competition for coactivator binding to NR (I), recruitment of SHP-associated corepressors (II), and inhibition of DNA binding (III). SHP can utilize these three inhibitory steps alternatively or sequentially in a cell type and target gene specific manner.
