Image Changes
I'd like to change the protein structure shown on the page to that based on 1ICE, because it better represents the uninhibited physiological caspase 1. I'd at the very least like to add the active form. Id also like to add the structure based on 5FNA, since it shows the filament formation of CARD domains.

Proposal for new changes
I am proposing a few changes to this page, as well as an overall overhaul of what's already written in order to make the page overall more coherent and consisten. The changes all belong to 3 of the already present subheaders, Structure, Interactions, and Function. The structure section will involve a description of the various domains present in the caspase 1 protein as well as the caspase 1 interacting proteins. The important structures in caspase 1 and its interacting proteins are Caspase recruitment domains (CARDs) and Pyrin domains (PYDs).

These structures then become very important going into the next section, interactions. Here, I will discuss how the inflammasome assembles through interactions of these domains, with PYD-PYD interactions allowing a sensor protein to bind to an adaptor protein, and CARD-CARD interactions which allows the inflammasome to attach to the caspase. While this is true for many types of inflammasomes, it is not true for all, as some sensors bind directly to caspase-1, through other interactions. The CARD domains also play an important role in inhibition, where several CARD only proteins (COPs) act to repress caspase functions.

Finally, I will provide detailed mechanisms for the activation of caspase 1 by the inflammasome formation, the cleavage of the IL-1beta and IL-18 precursors into mature cytokines, the cleavage of gasdermin D to induce pyroptosis, and the inhibition of caspase by the COPs. I will also discuss some of the downstream effects of the mature cytokines, the various sensors that are possible in the activation of caspase 1, as well a contested topic: whether or not pyroptosis is necessary for secretion of the mature cytokines.

Note: not all papers listed in the references will be necessary for these changes, but certainly more will be used than the 3 currently cited as of now. Many of the papers overlap in their descriptions of the various structures, interactions, and functions.

Please let me know what other changes I could add, or any changes in structure and organization you might suggest. Thanks! Bilguudei Naranbaatar (talk) 09:08, 5 May 2016 (UTC)
