Protein attributes
| Sequence length | 292 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Some isoforms may be involved in cardiolipin (CL) metabolism. Ref.6 Ref.7 |
| Subcellular location | Isoform 1: Membrane; Single-pass membrane protein. Isoform 2: Cytoplasm Probable. Isoform 3: Membrane; Single-pass membrane protein. Isoform 4: Membrane; Single-pass membrane protein. Isoform 5: Membrane; Single-pass membrane protein. Isoform 6: Cytoplasm Probable. Isoform 7: Membrane; Single-pass membrane protein. |
| Tissue specificity | High levels in cardiac and skeletal muscle. Up to 10 isoforms can be present in different amounts in different tissues. Most isoforms are ubiquitous. Isoforms that lack the N-terminus are found in leukocytes and fibroblasts, but not in heart and skeletal muscle. Some forms appear restricted to cardiac and skeletal muscle or to leukocytes. |
| Domain | The hydrophilic domain may serve as an exposed loop interacting with other proteins. |
| Involvement in disease | Barth syndrome (BTHS) [MIM:302060]: An X-linked disease characterized by dilated cardiomyopathy with endocardial fibroelastosis, a predominantly proximal skeletal myopathy, growth retardation, neutropenia, and organic aciduria, particularly excess of 3-methylglutaconic acid. Additional features include hypertrophic cardiomyopathy, isolated left ventricular non-compaction, ventricular arrhythmia, motor delay, poor appetite, fatigue and exercise intolerance, hypoglycemia, lactic acidosis, hyperammonemia, and dramatic late catch-up growth after growth delay throughout childhood. |
| Sequence similarities | Belongs to the taffazin family. |
