Target Background

(From Uniprot)
Probably involved in connections of major cytoskeletal structures to the plasma membrane. High molecular weight cytoskeletal protein concentrated at regions of cell-substratum contact and, in lymphocytes, at cell-cell contacts.
Gene References into Functions
  1. Low TLN1 expression is associated with invasion and metastasis in Hepatocellular Carcinoma. PMID: 29936723
  2. Calpain small subunit 1 (Capn4) overexpression increased the protein level of cleaved talin and and activated the focal adhesion kinase (FAK)/AKT/MAPK signaling in 786-O cells, while Capn4 silencing decreased the protein level of cleaved talin in Caki-1 cells. PMID: 29648579
  3. Talin-1 induces proliferation and migration of vascular smooth muscle cells obtained from patients with thoracic aortic dissection. PMID: 28637452
  4. Here, the authors show that cortical microtubule stabilization sites containing CLASPs, KIF21A, LL5beta and liprins are recruited to focal adhesions by the adaptor protein KANK1, which directly interacts with the major adhesion component, talin. Structural studies showed that the conserved KN domain in KANK1 binds to the talin rod domain R7. PMID: 27410476
  5. Vinculin head-tail interaction is required on soft substrates to destabilize vinculin and talin in FAs, and to allow hMSCs branching. Another module involves paxillin and FAK, which soft substrates also destabilize, but independently of vinculin head-tail interaction. This multi-modularity may be key to allow a versatile response to complex biomechanical cues. PMID: 27169142
  6. The central role of talin and vinculin in cell adhesions suggests that the disintegration of the tissue in atherosclerosis could be partially driven by downregulation of these genes, leading to loosening of cell-ECM interactions and remodeling of the tissue. PMID: 27816808
