Disease

[LDB3_HUMAN] Defects in LDB3 are the cause of cardiomyopathy dilated type 1C (CMD1C) [MIM:601493]. Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death.^[1] ^[2] Defects in LDB3 are the cause of left ventricular non-compaction type 3 (LVNC3) [MIM:601493]. Left ventricular non-compaction is characterized by numerous prominent trabeculations and deep intertrabecular recesses in hypertrophied and hypokinetic segments of the left ventricle. Defects in LDB3 are the cause of myopathy myofibrillar type 4 (MFM4) [MIM:609452]. A neuromuscular disorder characterized by distal and proximal muscle weakness with signs of cardiomyopathy and neuropathy.

Function

[LDB3_HUMAN] May function as an adapter in striated muscle to couple protein kinase C-mediated signaling via its LIM domains to the cytoskeleton.[:]

Publication Abstract from PubMed

Z band alternately spliced PDZ-containing protein (ZASP) is a sarcomere Z disk protein expressed in human cardiac and skeletal muscle that is thought to be involved in a dominant familial dilated cardiomyopathy. The N-terminal PDZ domain of ZASP interacts with the C terminus of alpha-actinin-2, the major component of the Z disk, probably by forming a ternary complex with titin Z repeats. We have determined the structure of ZASP PDZ by NMR and showed that it is a classical class 1 PDZ domain that recognizes the carboxy-terminal sequence of an alpha-actinin-2 calmodulin-like domain with micromolar affinity. We also characterized the role of each component in the ternary complex ZASP/alpha-actinin-2/titin, showing that the alpha-actinin-2/ZASP PDZ interaction involves a binding surface distinct from that recognized by the titin Z repeats. ZASP PDZ structure was used to model other members of the enigma family by homology and to predict their abilities to bind alpha-actinin-2.
