This domain is found in Transcription factor tau 138 kDa subunit from Saccharomyces cerevisiae (TFC3), which may play a role in linking tauA, tauB, and TFIIIB to regulate the formation of the RNA polymerase III pre-initiation complex. This entry represents its extended winged helix (eWH) domain, which is centrally located [1,2].	Domain
A	PF04182	B-block binding subunit of TFIIIC (B-block_TFIIIC)	B-block binding subunit of TFIIIC	-	Family
C	PF12660	Putative zinc-finger of transcription factor IIIC complex (zf-TFIIIC)	Putative zinc-finger of transcription factor IIIC complex	This zinc-finger domain is at the very C-terminus of a number of different TFIIIC subunit proteins. This domain might be involved in protein-DNA and/or protein-protein interactions [1].	Domain
