The muscle ankyrin repeat protein (MARP) family member Ankrd1/CARP is a part of the titin-mechanosensory signaling complex in the sarcomere and in response to stretch it translocates to the nucleus where it participates in the regulation of cardiac genes as a transcriptional co-repressor. Several studies have focused on its structural role in muscle, but its regulatory role is still poorly understood To gain more insight into the regulatory function of Ankrd1/CARP we searched for transcription factors that could interact and modulate its activity. Using protein array methodology we identified the tumor suppressor protein p53 as an Ankrd1/CARP interacting partner and confirmed their interaction both in vivo and in vitro We demonstrate a novel role for Ankrd1/CARP as a transcriptional co-activator, moderately up regulating p53 activity Furthermore, we show that p53 operates as an upstream effector of Ankrd1/CARP, by up regulating the proximal ANKRD1 promoter Our findings suggest that, be...sides acting as a transcriptional co-repressor, Ankrd1/CARP could have a stimulatory effect on gene expression in cultured skeletal muscle cells It is probable that Ankrd1 /CARP has a role in the propagation of signals initiated by myogenic regulatory factors (MRFs) during myogenesis
