What is zyxin?
What is Zyxin? Zyxin is enriched along actin filaments, stress fiber bundles, and at cell-cell or cell-matrix adhesion sites [1][2]. Zyxin is specifically found in more mature adhesions [3] and its absence in early [...]
What is vinculin?
What is Vinculin? Vinculin is a protein that couples, transmits, transduces, and regulates mechanical force between the cytoskeleton and adhesion receptors (reviewed in [1]). Vinculin frequently links adhesion receptors (e.g. integrins) to the contractile [...]
How is SRF signaling activated?
How is SRF signaling activated? Myocardin, MAL (or MRTF-A) and MRTF-B are the best-studied examples of MRTFs. In the cytoplasm, MRTFs exist in a stable complex with monomeric G-actin via RPEL domains, which exist [...]
What is the Hippo-YAP/TAZ tumor-suppressor pathway?
What is the Hippo-YAP/TAZ tumor-suppressor pathway? Mechanical cues control Hippo-YAP/TAZ tumor-suppressor pathway The Hippo signaling pathway is a complex network of proteins that controls organ size via regulation of cellular proliferation, survival and differentiation. [...]
What are guidance cues?
What are guidance cues? During neural development, highly motile structures on the developing neurites, called growth cones, are guided by signals from the extracellular environment. Guidance cues come in many different forms, from diffusible [...]
What is integrin extension?
What is integrin extension? Integrin extension Upon alteration in the transmembrane and their proximal domains, the bent headpiece extends in less than 1 second [1] with intermediate affinity for ligands. Two models- “switchblade” and [...]
