IHC image of Titin staining in a section of human normal frozen heart performed on a Leica Biosystems BOND® RX instrument using the standard protocol. The section was fixed in 10% paraformaldehyde (10 min) prior to staining. The section was incubated with ab284860, 0.5ugml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody. For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times. *Tissue obtained from the Human Research Tissue Bank, supported by the NIHR Cambridge Biomedical Research Centre

Supplementary information

Titin also known by its full name connectin is a giant protein that plays an essential mechanical role in muscle contraction. It is the largest known protein with a molecular mass of approximately 3800 kDa. Titin is expressed mainly in cardiac and skeletal muscle tissues where it functions as a molecular spring. It provides structural support and stability to the sarcomere which is the basic contractile unit of muscle tissues.
Biological function summary

This protein titin contributes significantly to the elasticity and extensibility of the muscle. Titin is an integral part of the thick filament in muscle fibers and interacts directly with actin and myosin linking them together. It belongs to the muscle protein complex forming the backbone around which other proteins assemble. Titin allows muscles to maintain passive tension and recoil after stretching contributing to muscle elasticity during contraction.

Pathways

Several important functions depend on the intricate arrangement of titin within the sarcomere structure. Titin is involved in the regulatory pathways of muscle assembly and integrity. An important pathway includes the mechanical signaling pathway where titin acts alongside proteins like myosin-binding protein C. Titin also contributes to muscle protein turnover by interacting with ubiquitin-proteasome pathway components though it primarily serves as a scaffold for other molecules within these complex pathways.

Mutations in the titin gene associate with a range of debilitating conditions especially cardiomyopathy and muscular dystrophy. In particular dilated cardiomyopathy often results from titin mutations affecting the heart muscle's function. Proteins like myosin can become dysregulated when titin function is compromised further contributing to the disorder's pathology. Investigating these connections helps reveal how alterations in titin impact muscle-related diseases.

Target data

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.
