The protein ras is involved in 25% of all cancers, and is attached to membranes through a covalent bond to a phospholipid. how does ras associate with membranes?

Through an anchor

Explanation;

-Protein Ras associates with the membranes through an anchor.

-Ras proteins are molecular switches that decide if and when cells divide inside our bodies, thus an impairment of their function may result in the formation of a tumor or cancer.

-Ras proteins require membrane association in order to be biologically active. Membrane anchorage of Ras proteins in the inner leaf- let of the plasma membrane is an important factor in their signaling and oncogenic potential.
