• common component of RNA polymerase 1 & RNA polymerase 3
• POLR1C is part of the pol core element with the central large cleft & probably a clamp element that moves to open & close the cleft (putative)

Structure

• belongs to the archaeal rpoD/eukaryotic RPB3 RNA polymerase subunit family

Compartment

nucleus (putative)

Alternative splicing
