Crystal structure of CC3 (TIP30): implications for its role as a tumor suppressor.
CC3 (TIP30) is a protein with pro-apoptotic and anti-metastatic properties. The tumor suppressor effect of CC3 has been suggested to result from inhibition of nuclear transport by binding to importin betas or by regulating transcription through interaction in a complex with co-activator independent of AF-2 function (CIA) and the c-myc gene. Previous biochemical studies indicated that CC3 has protein kinase activity, and a structural similarity to cAMP-dependent protein kinase catalytic subuni...Expand abstract
