ER, Golgi and Protein Processing
WebbFollowing translation, translocation or insertion into ER membrane, proteins are modified to assume their final structure and therefore function. Post-translational modifications change the chemical nature of the polypeptide chain through alterations to amino acid residues. Post-translational modifications take place in the ER and include ... WebbOne involves partial C-terminal truncation to generate a 51 kDa pyruvate kinase subunit which might have altered regulatory properties and the other involves phosphorylation … ttsh7 toto

WebbIn general, proteins bound for organelles in the endomembrane system (such as the ER, Golgi apparatus, and lysosome) or for the exterior of the cell must enter the ER at this … WebbThe heart is responsible for pumping blood, nutrients, and oxygen from its cavities to the whole body through rhythmic and vigorous contractions. Heart function relies on a delicate balance between continuous energy consumption and generation that changes from birth to adulthood and depends on a very efficient oxidative metabolism and the ability to … Webb1 feb. 1999 · To determine how env peptides are generated in the cytosol, we analyzed the processing of two TAP1/2-dependent epitopes containing N-linked glycosylation sites. In each case, processing involved glycosylation-dependent posttranslational modification of asparagine residues to aspartic acid. ttsh7 画像
