General annotation (Comments)
| Function | Key component in the assembly and functioning of adult and embryonic striated muscles and muscle tendons. By providing connections at the level of individual microfilaments, it contributes to the fine balance of forces between the two halves of the sarcomere. The size and extensibility of the cross-links are the main determinants of sarcomere extensibility properties of muscle. In non-muscle cells, seems to play a role in chromosome condensation and chromosome segregation during mitosis. Might link the lamina network to chromatin or nuclear actin, or both during interphase. Ref.1 Ref.2 Ref.5 Ref.6 Ref.7 Ref.8 Ref.9 |
| Subcellular location | Cytoplasm. Nucleus. Chromosome. Note: Uniformly distributed along condensed mitotic chromosomes. Ref.5 Ref.7 Ref.8 Ref.9 |
| Tissue specificity | Expressed in the mesoderm at stage 11, several hours before myoblast fusion, and persists in most muscle cells, somatic, visceral and pharyngeal muscles and their precursors, until the third instar. Also expressed in adult flight muscle Z-disks. Ref.1 Ref.2 Ref.5 Ref.6 Ref.8 Ref.9 |
| Developmental stage | Expressed both maternally and zygotically. Ref.9 |
| Disruption phenotype | Flies exhibit chromosome undercondensation, chromosome breakage, loss of diploidy, and premature sister chromatid separation. They also exhibit defects in myoblast fusion, muscle organization and gut morphogenesis. Ref.9 |
| Sequence similarities | Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. Contains 7 fibronectin type-III domains. Contains 53 Ig-like (immunoglobulin-like) domains. Contains 1 SH3 domain. Contains 7 TPR repeats. |
| Sequence caution | The sequence AAM11102.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
