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
