  • 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.
  • 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.
  • 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.

  • Developmental stage
    Expressed both maternally and zygotically.
  • Cellular localization
    Cytoplasm. Nucleus. Chromosome. Uniformly distributed along condensed mitotic chromosomes.
