DRL1 is an Elongator-associated factor that transiently interacts with the Elongator complex, facilitating its association with elongation-competent RNA polymerase II. It plays a significant role in regulating both meristem activity and organ growth, acting as a positive regulator of adaxial leaf patterning by modulating cell division and differentiation. DRL1 is essential for an early step in the synthesis of 5-carbamoylmethyl (ncm5) groups present on uridines (ncm5U) at the wobble position in tRNA.
