title: Muscle ankyrin repeat proteins: their role in striated muscle function in health and disease.
abstract: Remodeling is a stringently controlled process that enables adequate response of muscle cells to constant physical stresses. In this process, different kinds of stimuli have to be sensed and converted into biochemical signals that ultimately lead to alterations of muscle phenotype. Several multiprotein complexes located in the sarcomere and organized on the titin molecular spring have been identified as stress sensors and signal transducers. In this review, we focus on Ankrd1/CARP and Ankrd2/Arpp proteins,which belong to the muscle ankyrin repeat protein family (MARP) involved in a mechano-signaling pathway that links myofibrillar stress response to muscle gene expression. Apart from the mechanosensory function, they have an important role in transcriptional regulation, myofibrillar assembly, cardiogenesis and myogenesis. Their altered expression has been demonstrated in neuromuscular disorders, cardiovascular diseases, as well as in tumors, suggesting a role in pathological processes. Although analyzed in a limited number of patients, there is a considerable body of evidence that MARP proteins could be suitable candidates for prognostic and diagnostic biomarkers.
