Transcriptional activity of RBCK1 protein (RBCC protein interacting with PKC 1): requirement of RING-finger and B-Box motifs and regulation by protein kinases.

Abstract excerpt

The RBCK1 protein was recently identified as a protein kinase C-interacting protein with a new type of RBCC (RING-B-Box-Coiled-coil) region, possessing both DNA-binding and transcriptional activities unlike other proteins in the RBCC protein family (Tokunaga et al. Biochem. Biophys. Res. Commun. 244, 353-359, 1998). To identify protein motifs in the RBCC region of RBCK1 essential for the transcriptional activity,...
