NEET BIOLOGY

Detailed explanation-1: -The actin cytoskeleton plays a crucial role in in a variety of important cellular processes required for normal immune function, including locomotion, intercellular interactions, endocytosis, cytokinesis, signal transduction and maintenance of cell morphology.

Detailed explanation-2: -The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell’s parts.

Detailed explanation-3: -Cytoskeleton proteins such as spectrin, actin, tubulin, and other associated proteins essentially interact with integral membrane proteins through a set of intermediary proteins possessing multidomain structures that are able to provide specific sites for binding.

Detailed explanation-4: -Three main components of the cytoskeleton include actin filaments (also called microfilaments), microtubules and intermediate filaments. They are distinct structural compositions that exhibit slightly different yet interdependent functions.

Detailed explanation-5: -Chapter 11The Cytoskeleton and Cell Movement The cytoskeleton provides a structural framework for the cell, serving as a scaffold that determines cell shape and the general organization of the cytoplasm. In addition to playing this structural role, the cytoskeleton is responsible for cell movements.
