What is the primary function of integrin adhesion receptors in cellular structure?

Integrin adhesion receptors are located inside the nucleus and regulate gene expression.

Integrin adhesion receptors are involved in signal transduction and do not interact with the cytoskeleton.

Integrin adhesion receptors bind to the cytoskeleton and extracellular matrix, facilitating changes in cell shape and form.

Integrin adhesion receptors bind to steroid hormones and act as transcription factors.
