WebMass spectrometry-based proteomics is a powerful tool for identifying and quantifying proteins in biological samples. While it is routinely used for the characterization of simple cell line systems, the analysis of the cell specific proteome in multicellular organisms and tissues poses a significant challenge. Isolating a subset of cells from tissues requires mechanical … WebAug 10, 2024 · Nature Protocols - This protocol describes the MAC-tag approach, which combines affinity purification and biotinylation …
Proximity labeling - Wikipedia
WebAug 23, 2024 · In the biotin ligase-based (BioID) proximity labeling approach, BirA* (a mutant biotin ligase from E. coli) is attached to a polypeptide of interest (regarded as bait) and this combination is expressed in organisms or cultured cells.The BirA* releases biotinoyl-AMP into its immediate environment and the released compound labels lysine … WebJul 4, 2024 · BioID proximity labeling showed aberrant interactions between mutated IL2RG and ER/Golgi proteins causing mislocalization of the mutated IL2RG to the ER/Golgi interface. In conclusion, IL2RG p.(Pro58Ser) causes X-CID. Failure of IL2RG plasma membrane targeting may lead to atypical X-SCID. We further identified another carrier of … importance of learning the basics
