integrin alpha7-beta1 complex
Definition
Target type: cellularcomponent
An integrin complex that comprises one alpha7 subunit and one beta1 subunit. [PMID:12297042]
The integrin alpha7-beta1 complex is a transmembrane receptor that plays a crucial role in cell-matrix interactions. It is composed of two subunits: the alpha7 subunit and the beta1 subunit. The alpha7 subunit contains a large extracellular domain that interacts with the extracellular matrix (ECM) protein laminin. The beta1 subunit contains a transmembrane domain that anchors the complex to the cell membrane and a cytoplasmic domain that interacts with intracellular signaling molecules.
The cellular component of the integrin alpha7-beta1 complex is primarily the plasma membrane. This complex is located on the cell surface, where it binds to laminin in the ECM. Through this interaction, the integrin complex transmits signals from the ECM to the cell interior, influencing cell adhesion, migration, differentiation, and survival.
The integrin alpha7-beta1 complex also interacts with other cellular components, including the cytoskeleton. The cytoplasmic domain of the beta1 subunit binds to adaptor proteins, such as talin and kindlin, which link the integrin complex to the actin cytoskeleton. This connection allows the integrin complex to generate force and facilitate cell movement.
In addition to its role in cell adhesion and migration, the integrin alpha7-beta1 complex is also involved in various signaling pathways. Upon binding to laminin, the complex activates intracellular signaling cascades, leading to the activation of downstream effectors, such as kinases and transcription factors. These signaling pathways contribute to the regulation of gene expression, cell growth, and other cellular processes.
Overall, the integrin alpha7-beta1 complex is a crucial component of the cell membrane that plays a vital role in cell-matrix interactions. Its interactions with the ECM, cytoskeleton, and intracellular signaling pathways contribute to a wide range of cellular functions, including adhesion, migration, differentiation, and survival.'
