Key component in the assembly and functioning of vertebrate striated muscles. 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.1 Publication


In some isoforms, after the PEVK repeat region there is a long PEVK duplicated region. On account of this region, it has been very difficult to sequence the whole protein. The length of this region (ranging from 183 to 2174 residues), may be a key elastic element of titin.

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.


Enzyme regulationi

Full activation of the protein kinase domain requires both phosphorylation of Tyr-32341, preventing it from blocking the catalytic aspartate residue, and binding of Ca/CALM to the C-terminal regulatory tail of the molecule which results in ATP binding to the kinase.1 Publication
