Transcriptional repressor that plays a central role for embryogenesis and the pluripotency of embryonic stem (ES) cells. Sequence-specific DNA-binding factor that represses gene expression in pluripotent ES cells by directly binding to key genetic loci and recruiting epigenetic modifiers. Belongs to the THAP11 family. Interacts (via coiled coil domain) with HCFC1. Note: This description may include information from UniProtKB.
