The molecule, a type of ribonuclease, is found to latch onto the surface glycoproteins of a cancer cell, allowing it to enter and destroy the cell.
en.wikipedia.org A well-characterised example of this is the ribonuclease inhibitor, which binds to ribonucleases in one of the tightest known proteinprotein interactions.
en.wikipedia.org Human angiogenin diverged from ribonuclease, for example, and while the two paralogs remain similar in tertiary structure, their functions within the cell are now quite different.
en.wikipedia.org Multiple in vitro substrates for thioredoxin have been identified, including ribonuclease, choriogonadotropins, coagulation factors, glucocorticoid receptor, and insulin.
en.wikipedia.org Its function is to inhibit the ribonuclease activity of its binding partner barnase, with which it forms an extraordinarily tightly bound complex within the cell until barnase is secreted.
