The nuclear envelope is a membrane system which surrounds the nucleoplasm of eukaryotic cells. It is composed of the nuclear lamina, nuclear pore complexes and two nuclear membranes. The space between the two membranes is called the nuclear intermembrane space.
TFIIIC mediates tRNA and 5S RNA gene activation by binding to intragenic promoter elements. Upstream of the transcription start site, TFIIIC assembles the initiation complex TFIIIB-TFIIIC-tDNA, which is sufficient for RNA polymerase III recruitment and function. Part of the tauB domain of TFIIIC that binds boxB DNA promoter sites of tRNA and similar genes. Cooperates with sfc6 in DNA binding. Localizes to chromatin insulator sequence without recruiting RNA polymerase III and plays a role in nuclear organization. {By
