I trans membrane protein is located in the plasma membrane. It can be found in organelles such as the endoplasmic reticulum or on the phospholipd bilayer surrounding cells. Each end of the protein (the C-terminus (COOH) or N-terminus (NH2)) is located on opposite sides of the membrane. For example if located in the membrane of the ER, one one end of the protein would be in the ER lumen and the other in the cells cytoplasm.
The proteins are 'anchored' into the membrane by hydrophobic regions which are easily accommodated in the hydrophobic membrane.

∙ 14y agoA trans-membrane protein is - as the name implies (trans = across in latin) - a protein, which crosses a biological membrane, such as the outer cell membrane or the mitochondrial membrane. Three examples of important trans-membrane proteins are: the Na/K-ATPase, P-glycoprotein, and the insulin receptor.

What type of proteins don't go through the bilayer?
It important that some proteins extend all the way through the bilayer of a plasma membrane. This is to offer protection to the cell and also facilitate the transport of various substances in and out of the cell.
What are facts about integral membrane proteins?
They are usually transmembrane proteins.
What are channels in the pumps in the cell membrane mad of?
These are proteins. Transmembrane proteins span the entire membrane.
What are integral and transmembrane proteins?
the proteins that protrude from both surfaces of the bilayer
What component of a phospholipid membrane helps the cell interact with its polar watery environment?
Membrane proteins.

Claudin

What component of a phospholipid membrane helps the cell interact with its polar watery environment?
Membrane proteins.
Are integrins embedded in the lipid bilayer?
Yes they are, as well as glycoproteins, integral proteins, and transmembrane proteins. Peripheral proteins however are not embedded in the lipid bilayer.
What is an anoctamin?
An anoctamin is any of a group of transmembrane proteins associated with the channelling of chloride ions.
Cellular adhesion molecules are?
Cell adhesion molecules are groups of transmembrane proteins that mediate.
What are the channels in the cell membrane made of?
Most channels are made of specialized transmembrane proteins.
What is a cadherin?
A cadherin is any of a class of transmembrane proteins important in maintaining tissue structure.
What is another name for integration?
Another name for integral proteins is integral membrane proteins.Most are transmembrane proteins, which span the entire depth of the membrane.
