Also known as SPRYD2DKFZp451G223TRIM76

Summary

CMYA5 (cardiomyopathy associated 5, HGNC:14305) is a protein-coding gene on chromosome 5q14.1, encoding Cardiomyopathy-associated protein 5 (Q8N3K9). May serve as an anchoring protein that mediates the subcellular compartmentation of protein kinase A (PKA) via binding to PRKAR2A.

Predicted to enable identical protein binding activity and protein phosphatase inhibitor activity. Predicted to act upstream of or within negative regulation of calcineurin-NFAT signaling cascade and regulation of skeletal muscle adaptation. Predicted to be located in several cellular components, including costamere; perinuclear region of cytoplasm; and sarcoplasmic reticulum. Predicted to be active in cytoplasm.

Function. May serve as an anchoring protein that mediates the subcellular compartmentation of protein kinase A (PKA) via binding to PRKAR2A. May function as a repressor of calcineurin-mediated transcriptional activity. May attenuate calcineurin ability to induce slow-fiber gene program in muscle and may negatively modulate skeletal muscle regeneration. Plays a role in the assembly of ryanodine receptor (RYR2) clusters in striated muscle.

Subunit / interactions. Interacts with PRKAR2A. Interacts with ACTN2 and DTNBP1/dysbindin. Interacts with DES. Interacts with DMD/dystrophin. Interacts with the calcineurin catalytic subunit PPP3CA. Interacts with TTN. Interacts with CAPN3; this interaction, which results in CMYA5 proteolysis, may protect CAPN3 from autolysis. Interacts with FSD2. Identified in a complex composed of FSD2, CMYA5 and RYR2.

Subcellular location. Nucleus. Sarcoplasmic reticulum. Cytoplasm. Perinuclear region. Myofibril. Sarcomere. M line.

Tissue specificity. Expressed in skeletal muscle; at a strong level and in heart.

Post-translational modifications. Phosphorylated by PKA.

Domain organisation. Amphipathic helix regions act as an anchoring domain for PKA, and appear to be responsible of the interaction between myospryn and PRKAR2A.

Induction. Down-regulated in muscle cell lines derived from patients with Duchenne muscular dystrophy (DMD).
