What are examples of integral membrane proteins?
Examples of integral membrane proteins:
- Insulin receptor.
- Some types of cell adhesion proteins or cell adhesion molecules (CAMs) such as integrins, cadherins, NCAMs, or selectins.
- Some types of receptor proteins.
- Glycophorin.

What is the role of the ion channel?
Ion channels are transmembrane proteins whose canonical function is the transport of ions across the plasma membrane to regulate cell membrane potential and play an essential role in neural communication, nerve conduction, and muscle contraction.
Are ion channels integral proteins?
In short, ion channels are integral membrane proteins with characteristic features that allow them to assemble into multimolecular aggregates.
What is the function of integral protein in cell membrane?
Integral membrane proteins reside within the bilayer membranes that surround cells and organelles, playing critical roles in movement of molecules across them and the transduction of energy and signals.
What are ion channel proteins?
Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient.
What is the role of integral proteins?
What is the KH domain of DNA?
The K Homology (KH) domain is a protein domain that was first identified in the human heterogeneous nuclear ribonucleoprotein (hnRNP) K. An evolutionarily conserved sequence of around 70 amino acids, the KH domain is present in a wide variety of nucleic acid-binding proteins.
What is an integral protein?
Integral Protein Definition. An integral protein, sometimes referred to as an integral membrane protein, is any protein which has a special functional region for the purpose of securing its position within the cellular membrane.
What is the KH domain of Vigilin?
Structure of a KH domain from the human protein vigilin. The K Homology (KH) domain is a protein domain that was first identified in the human heterogeneous nuclear ribonucleoprotein (hnRNP) K. An evolutionarily conserved sequence of around 70 amino acids, the KH domain is present in a wide variety of nucleic acid-binding proteins.
Do both integral and peripheral proteins contain hydrophilic components?
Both integral and peripheral proteins contain hydrophilic components. Both integral and peripheral proteins perform important functions in the cell. Integral Proteins: Integral proteins are proteins that are permanently attached to the plasma membrane.
