Conditional T cell engager prodrugs are inert in normal tissues but on entry into the proteolytically active tumor microenvironment, their enzyme-sensitive linkers (neon green) are hydrolyzed, allowing engagement of their anti-CD3 domains (red) with the T cell …

Webb1 maj 2002 · SREBPs: activation through proteolytic processing SREBPs belong to the basic helix-loop-helix–leucine zipper (bHLH-Zip) family of transcription factors, but they differ from other bHLH-Zip proteins in that they are synthesized as inactive precursors bound to the endoplasmic reticulum (ER) ( 1, 5 ). Webb7 sep. 2024 · Proteolytic Activation is the activation of an enzyme by peptide cleavage. The enzyme is initially transcribed in a longer, inactive form. In this enzyme regulation process, the enzyme is shifted between the inactive and active state. Irreversible conversions can occur on inactive enzymes to become active.
