The mechanosensitive ion channel which drives cell division in epithelial cell layers is:
A)a trimer of Piezo1 subunits forming a channel with a central pore and two long curved arms
B)a dimer of Piezo1 subunits forming a channel with a central pore and two long curved arms
C)a trimer of Piezo1 subunits forming a channel with a central pore and three long curved arms
D)a trimer of Piezo2 subunits forming a channel with a central pore and two long curved arms
E)a dimer of Piezo2 subunits forming a channel with a central pore and three long curved arms

Question

Quizplus · Accepted Answer

Piezo1 is known to form a trimeric structure, with each subunit contributing to a central pore and extending three long curved arms, which is essential for its function as a mechanosensitive ion channel.
