The C-terminus (also known as the carboxyl-terminus, carboxy-terminus, C-terminal tail, carboxy tail, C-terminal end, or COOH-terminus) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH). When the protein is translated from messenger RNA, it is created from N-terminus to C-terminus. The ...
Group I proteins have the N terminus on the far side and C terminus on the cytosolic side. Group II proteins have the C terminus on the far side and N terminus in the cytosol. However final topology is not the only criterion for defining transmembrane protein groups, rather location of topogenic determinants and mechanism of assembly is ...
Usually, it is the C-terminal domain of the MAP that interacts with tubulin, while the N-terminal domain can bind with cellular vesicles, intermediate filaments or other microtubules. MAP-microtubule binding is regulated through MAP phosphorylation. This is accomplished through the function of the microtubule-affinity-regulating-kinase (MARK ...
The C-terminus can also be blocked (thus, neutralizing its negative charge) by amination. glycosyl phosphatidylinositol (GPI) attachment Glycosyl phosphatidylinositol (GPI) is a large, hydrophobic phospholipid prosthetic group that anchors proteins to cellular membranes .
Group I proteins have the N terminus on the far side and C terminus on the cytosolic side. Group II proteins have the C terminus on the far side and N terminus in the cytosol. Three-dimensional structures of ~160 different integral membrane proteins have been determined at atomic resolution by X-ray crystallography or nuclear magnetic resonance ...

The soluble resident protein will remain in the ER as long as it contains a KDEL signal sequence on the C-terminal end of the protein. However, since vesicle budding is such a dynamic process, and there is a high concentration of soluble proteins in the ER, soluble proteins are inadvertently transported to the cis-golgi via COPII coated vesicles.
