The Pol Theta C-terminal domain refers to a specific region found in the DNA polymerase theta enzyme (Pol θ). Pol θ is a specialized DNA polymerase that plays a role in DNA repair processes, particularly in the repair of double-stranded DNA breaks. The C-terminal domain of Pol θ is located at the end of the enzyme's protein chain and is involved in various functions related to DNA repair. It contains specific motifs and regions that interact with other proteins and DNA molecules to facilitate repair processes.
