The key components of desmosomes are cadherins and__________.

a. actin

b. microfilaments

c. intermediate filaments

d. microtubules

Short Answer

Expert verified

The key components of desmosomes are cadherins and intermediate filaments.

Step by step solution

01

Explanation

Actin is an intracellular protein that aids in cell contraction as well as cell shape and structure regulation. So, option a is incorrect.

Microfilaments are made up of a protein named actin which helps in cell movement. Hence, option b is wrong as well.

They are the major component of the cytoskeleton which helps in cell movement, growth, and signaling. Option d is incorrect.

Desmosomes are made up of a network of cadherin proteins, linker proteins, and keratin intermediate filaments known as desmosome-intermediate filament complexes (DIFC). Thus, option c is correct.

02

Conclusion

Desmosomes are made up of cadherins and intermediate filaments which helps in organizing the internal structure of the cell.
