Abstract

The ANKRD1/CARP gene encodes a muscle-specific protein which has been implicated in transcriptional regulation and myofibrillar assembly. Several features at both the mRNA and protein levels define ANKRD1 as a gene whose expression is tightly regulated, and deregulated expression of this protein has been recently associated to human congenital heart disease. It is therefore crucial to define the intracellular pathways that regulate the ANKRD1 protein's steady-state levels. Here, we show that ANKRD1 is a short-lived protein whose levels are tightly regulated by the 26S proteasome. In addition, a critical role for a putative PEST motif was established, although other degrons within the ANKRD1 protein are likely implicated in the control of its intracellular levels.
