Associations of Tln1 with chemical compounds

  • Talin binding disrupts the salt bridge between the alpha/beta tails, leading to tail separation and integrin activation [14].
  • Indeed, binding of talin present in rat brain extracts to a glutathione S-transferase integrin beta1-cytodomain polypeptide was inhibited by the PIP kinase peptide [10].
  • Recently, the integrin beta3 cytodomain and phosphatidylinositol phosphate (PIP) kinase type 1gamma (a phosphatidylinositol 4,5-bisphosphate-synthesizing enzyme) were shown to bind to the talin FERM domain (subdomain F3) [10].
  • Two tyrosine residues flanking the SPLH motif (Tyr-644 and Tyr-649) have been implicated in the regulation of talin binding [15].
  • Modeling studies suggest that phosphorylation of Tyr-649 will likewise have little effect on talin binding, whereas phosphorylation of the SPLH serine is predicted to be strongly disruptive [15].
 

Physical interactions of Tln1

  • Phosphatidylinositol phosphate kinase type 1gamma and beta1-integrin cytoplasmic domain bind to the same region in the talin FERM domain [10].
  • Isolation of peptides from phage-displayed random peptide libraries that interact with the talin-binding domain of vinculin [8].
  • We show that talin physically interacts with CR3/alpha(M)beta(2) and that this interaction involves the talin head domain and residues W747 and F754 in the beta(2) integrin cytoplasmic domain [16].
 

Enzymatic interactions of Tln1

 

Regulatory relationships of Tln1

  • Talin immunostaining was widespread throughout control cells but was localized to the periphery 8 h after treatment with TPA or with inhibitors of PKC and calpain [18].
  • This suggests that the local association of talin with these sites is induced by the cytoplasmic tail of beta 1 integrin receptor presented by the chimeric protein [19].
  • These combined results suggest a model in which the reciprocal actions of Src tyrosine kinase and Shp-1 tyrosine phosphatase dynamically regulate the association between PIPKI gamma661 and talin [20].
