In 1970, Günter Blobel conducted experiments on protein translocation across membranes. Blobel, then an assistant professor at Rockefeller University, built upon the work of his colleague George Palade. Palade had previously demonstrated that non-secreted proteins were translated by free ribosomes in the … Visa mer This article deals with protein targeting in eukaryotes unless specified otherwise. Protein targeting or protein sorting is the biological mechanism by which proteins are transported to their appropriate destinations within … Visa mer Since the translation of mRNA into protein by a ribosome takes place within the cytosol, proteins destined for secretion or a specific Visa mer Protein transport is defective in the following genetic diseases: • Mohr–Tranebjaerg syndrome • Zellweger syndrome • Adrenoleukodystrophy (ALD). • Refsum disease Visa mer Signal peptides serve as targeting signals, enabling cellular transport machinery to direct proteins to specific intracellular or extracellular locations.
