How are proteins modified after translation
WebStudies in rat aortic smooth muscle cells identified serotonylation of various proteins such as α-actin, β-actin, γ-actin, myosin heavy chain, and protein filamin A (Watts, Priestley, & Thompson, 2009). β-actin and γ-actin are expressed in the CNS and actin was shown to be monoaminylated in primary glial culture (Hummerich et al., 2015) and may be modified … WebFollowing 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 ...
