Integrin cytoplasmic domains as connectors to the cell's signal transduction apparatus

Matrix Biol. 1997 Oct;16(4):153-63. doi: 10.1016/s0945-053x(97)90003-2.


Integrins mediate the bidirectional transfer of signals across the plasma membrane. Integrin cytoplasmic domains provide one pathway linking integrin engagement with the cell's signal transduction apparatus. Recent structure-function studies have defined regions of beta cytoplasmic domains required for integrin function and have identified distinct roles for individual alpha cytoplasmic domains in regulating cell behavior. Newly identified proteins that bind to integrin alpha and beta cytoplasmic domains have provided new insights and new questions into the mechanisms involved in integrin signaling.
