| DNA/RNA |
| Transcription | Various splicing forms, in particular KIAA0477 and KIAA0454 |
| Protein |
| Description | Large protein; some isoforms having more than 2300 aminoacids (62 kDa and 230-250 kDa proteins in the rat ortholog); mainly composed of alpha-helical and coiled-coil structures; includes a leucine zipper in N-term, a dynactin-centractin binding domain, and a helix-loop-helix. |
| Expression | in heart and skeletal muscles; little expression in other tissues |
| Localisation | Cytoplasm in the Golgi/centrosomal area in non muscle cells and nucleus; in the sarcomeres of muscle cells |
| Function | Interacts with the cyclic nucleotide phosphodiesterase PDE4D, enzymes that degrade and inactivate cAMP; may oligomerize |
| Homology | With the Drosophila centrosomin (a component of the centrosome and the mitotic spindle) |
| Implicated in |
| Entity | t(1;5)(q22;q33) in chronic eosinophilic leukemia --> PDE4DIP - PDGFRB |
| Note | KIAA0477 isoforms was found involved in the hybrid gene / fusion protein. |
| Disease | Rare disease mainly found in infants. |
| Prognosis | Treatment with imatinib may be relevant. |
