May play a role in cell death control. Acts as a transcriptional repressor. Has been shown to repress transcription of SRF in vitro and so may play a role in heart development (By similarity). Interacts with XIAP. Some staining in the cytosol; cytosolic localization is reduced in staurosporine-induced cell death. Broadly expressed in the embryo during the early stages of organogenesis with highest levels in dorsal root ganglia and little or no expression in liver and skin. The C-terminal region mediates transcriptional repression. Belongs to the TCF25 family.
