Question

As described in lecture, cells form actin filaments in particular regions of the cell in part because they nucleate filament formation at particular times and places within cells and in part because they inhibit the formation of filaments that are "randomly" nucleated. What protein(s) is/are responsible for inhibiting the elongation of filaments that are randomly nucleated?

Answer 1

The protein responsible for inhibiting the elongation of filaments is the Actin Filament Capping Protein (CapZ)

Step-by-step explanation:

CapZ is a protein capable of inhibiting the elongation of filaments by binding actin to its ends
