**NCBI Gene Summary**: This gene is a member of the muscle ankyrin repeat protein (MARP) family and encodes a protein with four tandem ankyrin-like repeats. The protein is localized to the nucleus, functioning as a transcriptional regulator. Expression of this protein is induced during recovery following starvation. [provided by RefSeq, Jul 2008]

**GeneCards Summary**: ANKRD23 (Ankyrin Repeat Domain 23) is a Protein Coding gene. Diseases associated with ANKRD23 include Glioblastoma Proneural Subtype and Total Anomalous Pulmonary Venous Return 1. Among its related pathways are 2q11.2 copy number variation syndrome and Cardiomyocyte signaling pathways converging on Titin. Gene Ontology (GO) annotations related to this gene include titin binding.

**UniProtKB/Swiss-Prot Summary**: May be involved in the energy metabolism. Could be a molecular link between myofibrillar stretch-induced signaling pathways and muscle gene expression.
