The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 58 kDa (predicted molecular weight: 60 kDa).
Ctk1 is the catalytic subunit of CTDK-1 that hyperphosphorylates the C-terminal repeat domain (CTD) of RNA polymerase II largest subunit. CTDK-I is localized to the nucleolus. Ctk1 also co-precipitates with RNA polymerase I co-indicating a direct interaction between RNA polymerase I and Ctk1. Therefore, CTDK-I appears to play a role regulating distinct nuclear transcriptional machineries.
