SPOCD1 Contains 1 SPOC domain. Contains 1 TFIIS central domain.The Split ends (Spen) family are large proteins characterised by N-terminal RNA recognition motifs (RRMs) and a conserved SPOC (Spen paralog and ortholog C-terminal) domain.The widely distributed DIO (Death inducer-obliterator) family is related to cancer and apoptosis and offers new clues about SPOC domain functionality.
TFIIS is a transcription elongation factor, which directly binds the transcription motor, RNA Polymerase II and allows it to read through various transcription arrest sites. TFIIS, a transcription elongation factor, and its affect on proliferation of cancer cells in culture. Knockdown of TFIIS reduced cancer cell proliferation in breast, lung and pancreatic cancer cell lines.
