Some ___ link to actin and form actin-linked cell–matrix junctions.
Understand the Problem
The question is asking about a biological concept related to proteins or cellular components that interact with actin to form specific junctions in cells, specifically cell–matrix junctions.
Answer
integrins
The final answer is integrins.
Answer for screen readers
The final answer is integrins.
More Information
Integrins are transmembrane receptors that facilitate cell-ECM adhesion by linking the extracellular matrix to the actin cytoskeleton inside cells. This connection is crucial for cell signaling and structural integrity.
Tips
A common mistake is to confuse cell-cell junctions like cadherins with cell-matrix junctions that involve integrins.
