Which of the following best describes the structure of integrins?
A)Integrins cluster in cis until coming into contact with another cell,where a trans network forms.
B)Integrins are homodimers of subunits expressed in a cell-type specific manner,
C)A single integrin subunit forms heterophilic interactions with fibronectin and laminin.
D)Integrins are heterodimers composed of α and β subunits.

Question

Quizplus · Accepted Answer

Integrins are composed of two subunits, α and β, which form a heterodimer. This heterodimer configuration allows for diversity in integrin function by varying the combinations of the α and β subunits.
