Background

Interleukin-1 receptor type 2 (IL1R2) is also known as CD121 antigen-like family member B (CDw121b), IL-1 type II receptor, Interleukin-1 receptor type II, belongs to the interleukin-1 receptor family. Two distinct types of IL1 receptors which are able to bind IL1 specifically have been identified, designated as IL1RI (IL1RA) and IL1RII (IL1RB). IL1R2 is non-signaling receptor for IL1A, IL1B and IL1RN, reduces IL1B activities. Serves as a decoy receptor by competetive binding to IL1B and preventing its binding to IL1R1. IL1R2 modulates cellular response through non-signaling association with IL1RAP after binding to IL1B. IL1R2 (membrane and secreted forms) preferentially binds IL1B and poorly IL1A and IL1RN. The secreted IL1R2 recruits secreted IL1RAP with high affinity; this complex formation may be the dominant mechanism for neutralization of IL1B by secreted/soluble receptors. It has been suggested that the type II receptor, either as the membrane-bound or as the soluble form, serves as a decoy for IL-1 and inhibits IL-1 action by blocking the binding of IL-1 to the signaling type I receptor complex. Recombinant IL-1 soluble receptor type II is a potent antagonist of IL-1 action.

As advertised
Color: Green Orange
Did exactly what they needed. Made the remote slightly larger so it is easier to use and less slippery.

Pretty good...
Color: Red
Red color is kind of an orange-red. Hm... Came with some kind of dust on it. Once cleaned off it's not as slippery, yet still slips on just fine. Protects the remote - and your hands from the remote's hard edges. The raised bumps on the back make it easier to pickup - without digging your fingernails into cushions or carpets as you "scoop."

Very handy to have to spot them easily
Color: Dark Blue
Love the cases, have a different color on each rooms tv. Hopefully it will protect from a drop as that is what prompted me to buy it. We cracked the screen on our last remote and they are expensive to replace. Good price

THESE TWO REMOTE CADDIES ARE FANTASTIC
Color: Beige, Color: Beige
I bought both of these caddies. Picture 1 shows it in my living room - TV Remote, Cable Remote, Ceiling Fan Remote and glasses. I love the little handle that I can pick up when I need to clean the glass table. Picture 2 shows the three slot remote. I put this in bed with me at night. I am older now and I need my phone on my bed at night so in this caddy I have my phone and ceiling remote fan. Also it is a good weight so it will not fall. These caddies are so well built and so nice to look at. If you need a remote caddy you will love either of these.
