Paper by Ueda et al "Rap1 organizes lymphocyte front-back polarity via RhoA signaling and talin1" in iScience @iScience

The role of talin1 in cell polarization, downstream of Rap1, seems to be independent of talin binding to integrins and of integrin adhesion

#introduction
Hello, this is Jose M de Pereda and I run a research group at the Center for Cancer Research in #Salamanca (Spain) (#CSIC #USAL).
We study the structural and mechanistic basis of #integrin based #CellAdhesion complexes (mostly #Hemidesmosomes) and of #Rap1 signaling. Knowing in detail how these molecular systems work is essential to understand how they are altered in diseases.
We do multidisciplinary research: #StructuralBiology #Biochemistry, #Biophysics and a bit of #CellBiology
