Cell junctions are especially important in enabling communication between neighboring cells via specialized proteins called communicating junctions.

Certain specialized proteins called clotting factors aid the blood to clot.

To thwart these problems, the eukaryotic replisome contains specialized proteins that are designed to regulate the helicase activity ahead of the replication fork.

DNA binding sites are often associated with specialized proteins known as transcription factors, and are thus linked to transcriptional regulation.

Despite the enormous complexity and large number of specialized proteins in a proteasome, evolution readily explains its origins through gene duplication and specialization.

Replication, like all cellular activities, requires specialized proteins for carrying out the job.

Freezing is made possible by specialized proteins and glucose, which prevent intracellular freezing and dehydration.

Eventually the macrophages communicate with and activate other specialized proteins involved in inflammation and immunity.

Quality control is so important that thousands of specialized proteins, some called chaperones, carry out the recycling task.

Enzyme catalysis is the catalysis of chemical reactions by specialized proteins known as enzymes.
