Background

Interleukin-1 receptor accessory protein (IL1RAP or IL-1RAcP) is also known as Interleukin-1 receptor 3 (IL-1R-3 or IL-1R3), C3orf13, which belongs to the interleukin-1 receptor family. It serves as a non-ligand-binding component of the receptors for IL-1 alpha, IL-1 beta, IL-33, and IL-36. Mature human IL-1 RAcP consists of a 347 amino acid (aa) extracellular domain (ECD) with three Ig-like domains, a 21 aa transmembrane segment, and a 182 aa cytoplasmic domain. Coreceptor with IL1R1 in the IL-1 signaling system. Associates with IL1R1 bound to IL1B to form the high affinity interleukin-1 receptor complex which mediates interleukin-1-dependent activation of NF-kappa-B and other pathways. Signaling involves the recruitment of adapter molecules such as TOLLIP, MYD88, and IRAK1 or IRAK2 via the respective TIR domains of the receptor/coreceptor subunits. Does not bind to interleukin-1 alone; binding of IL1RN to IL1R1, prevents its association with IL1R1 to form a signaling complex. The cellular response is modulated through a non-signaling association with the membrane IL1R2 decoy receptor. Coreceptor for IL1RL1 in the IL-33 signaling system. Can bidirectionally induce pre- and postsynaptic differentiation of neurons by trans-synaptically binding to PTPRD.

Super Fun
Color: Green
One of the most entertaining things you could buy. The dogs go crazy over it and have so much fun. It's a bit loud on hard floors, but honestly worth it for the laughs. Seems pretty durable too. I have 2 labs; one started out uninterested and the other started off scared of it, but not too long after, they both started going crazy, tossing and carrying it around while it shook.

Great for dog who loves chewing small “tags” on stuffies
Size: Rabbit & Pig
My dog loves chewing the small tags or ears etc on plushies. He will pick one ear to chew on the little stuffed dogs from Petco, chew it until it’s starting to get shredded and I have to cut it off, then switch to the other. I picked these toys specifically because they have SIX little tag-like parts that stick out, not just the two ears. He loves them! He is a 10 lb maltipoo and can easily grab and run with these. Loves the crinkle paper inside, loves the squeaker in the head, and LOVES the little parts that stick out for him to chew. We just got them today so time will tell if they are durable, but they seem well constructed and he’s happy, so I’m happy. Update: it’s been a week. I gave him one of the toys and he of course chose one ear to focus all his chewing on. That ear has been chewed and chewed and it is just getting to the point it’ll need to be trimmed off soon due to raggedness. Then he’ll still have five little nubs left on this toy to chew. So it should take him at least 6 weeks to chew all of them. By comparison, when we get cheap stuffies on Amazon, usually both ears are totally finished within a week or ten days. This is definitely more durable and worth the money!
