doi: 10.1016/j.virol.2020.06.004

Figure Lengend Snippet: Biochemical analyses for S-palmitoylation on swine IFITM1. (a) The palmitoylation/depalmitoylation is a dynamic reversible reaction in which the palmitoyl thioester group is covalently connected to coenzyme A(CoA), is transferred to cysteine by palmitoyl acyl transferase (PAT). (b) The principle of acyl-PEGyl exchange gel shift. (c) Molecular structure of 2-bromopalmitic acid (2BP). (d) S-palmitoylated sIFITM1 was monitored through APEGS method mass-shift based detection. The cell lysates are incubated with TCEP, and free cysteine residues are protected with NEM. S-fatty acid groups of sIFITM1 are replaced by 5 KDa mPEG-Mal through two subsequent reactions, a reduction mediated by NH 2 OH results to cysteines exposure and then a ligation with mPEG-Mal. Proteins are subjected to SDS-PAGE and then measured by Western blot. The number 10 and 100 represented the μM concentration of 2-BP. The number of PEGylation exchange is indicated by asterisks (*). The lower two panels were SDS-PAGE of whole-cell lysate input fraction from cells used in upper APEGS analysis. Immunoblotting was performed with anti-FLAG and anti-actin. (e) The relative intensity of the palmitoylated and unpalmitolated sIFITM1. The relative intensity was a ratio of average intensity of estimates (n = 5) worked out according to the intensity of different mass-shift bands of sIFITM1 measured by Image Pro Plus software. The expression of actin and sIFITM1 in whole lysate were taken as important consideration in data processing.
