Rab39a Binds Caspase-1 and Is Required for Caspase-1-dependent Interleukin-1β Secretion*
Interleukin-1beta (IL-1beta) is an important pro-inflammatory cytokine that is secreted by unconventional means in a caspase-1-dependent manner. Using a one-step immunoprecipitation approach to isolate endogenous caspase-1 from the monocytic THP1 cell line, we identified previously undescribed binding partners using mass spectrometry. One of the proteins identified was Rab39a, a member of the R...

متن کاملActive Caspase-1 Is a Regulator of Unconventional Protein Secretion
Mammalian cells export most proteins by the endoplasmic reticulum/Golgi-dependent pathway. However, some proteins are secreted via unconventional, poorly understood mechanisms. The latter include the proinflammatory cytokines interleukin(IL)-1beta, IL-18, and IL-33, which require activation by caspase-1 for biological activity. Caspase-1 itself is activated by innate immune complexes, the infla...
متن کاملProtein Secretion: Unconventional Exit by Exophagy
Certain secreted proteins bypass the canonical exit pathway from cells. Two studies now shed light on the unconventional secretion route taken by the yeast acyl-coenzyme A-binding protein: this protein is sequestered into autophagic vesicles that are re-routed to the plasma membrane where their content is released to the extracellular space.
متن کاملPannexin-1-dependent caspase-1 activation and secretion of IL-1β is regulated by zinc
Inflammatory processes induced by IL-1beta are critical for host defence responses, but are also implicated in disease. Zinc deficiency is a common consequence of, or contributor to, human inflammatory disease. However, the molecular mechanisms through which zinc contributes to inflammatory disease remain largely unknown. We report here that zinc metabolism regulates caspase-1 activation and IL...
