Web1 May 2024 · Tail-anchored (TA) proteins contain a single transmembrane domain (TMD) at the C-terminus that anchors them to the membranes of organelles where they mediate critical cellular processes. Accordingly, mutations in genes encoding TA proteins have been identified in a number of severe inherited disorders. Web21 Dec 2001 · Tail-anchored proteins can generally be recognised by the presence of a single, presumably helical, transmembrane segment at their C-terminus. This transmembrane segment ranges from 15 to 22 amino acids in length and is typically followed by a relatively short lumenal domain. Web30 Sep 2024 · A putative posttranslational role of SRP has been suggested for some eukaryotic and bacterial tail-anchored (TA) proteins [69–73]. However, at least some bacterial TA proteins, like SciP , contain N-terminal amphipathic helices that could serve as cotranslational recognition sites for SRP [74, 75]. rectangular wicker laundry basket
