Background

Interleukin-29, is a secreted protein which belongs to the IL-28 / IL-29 family, and is a cytokine with immunomodulatory activity. It is also known as cytokine Zcyto21, Interferon lambda-1, IFN-lambda-1, IFNλ1, IL-29 and IFNL1, and is highly similar in amino acid sequence to the IL-28, the other type III interferon. Human IL29 cDNA encodes a 200 amino acid (aa) residue precursor protein with a putative 19 aa signal peptide and a 181 aa mature protein, which is a monomer in solution. It shares 67% and 69% aa sequence identity with human IL28A and IL28B, respectively. IL-29 plays an important role in host defenses against microbes and its gene is highly upregulated in cells infected with viruses and also may play a role in antiviral immunity. Interleukin-29 / IL-29 up-regulates MHC class I antigen expression. It is a Ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IL28RA. The ligand/receptor complex seems to signal through the Jak-STAT pathway.

Works great, keeps the light out of my eyes and easy to put together
Size: 1 Panel, Size: 1 Panel
I got this room divider in and it works great. It’s really easy to put together you don’t even need tools. I really like that it’s not see through, it’s not a black out curtain but it keeps light out pretty good. I absolutely hate my bedroom layout there’s no bathroom door. My girlfriend and I have different work schedules so I’m trying to sleep while she’s getting ready for work and the light shines right in my eyes. This divider keeps the light out of my eyes and that’s exactly what I was hunting for. I also like that you can adjust the length. I took one of the bars out to make it a little shorter and it worked great. I would recommend this room divider.

Game-Changer for My Space!
Color: White, Size: 4 Panel Basic
I recently purchased the Kecreque 4-Panel Room Divider, and it has completely transformed my living area. At 88" wide, it provides ample coverage, creating a private nook in my open-concept home. The white polyester fabric is not only sleek and modern but also wrinkle-resistant and easy to clean—just a quick wipe with a damp cloth, and it looks brand new. Assembly was a breeze; I had it set up in about 20 minutes. The metal frame feels sturdy and durable, and the three extra-wide metal feet offer excellent stability, ensuring it doesn't tip over easily. I love how the panels are connected with flexible buckles, allowing me to adjust the configuration to suit my needs—be it a straight line or an angled setup. This divider has been perfect for creating a dressing area in my bedroom, and I've also used it to section off a workspace in my living room. Its versatility is unmatched, and it folds down compactly when not in use, making storage hassle-free. If you're looking for a stylish, functional, and easy-to-use room divider, I highly recommend this one. It's been a fantastic addition to my home!

Sturdy and Functional
Color: White, Size: 4 Panel Basic
I got this to replace a poor quality divider that I tried first, and this thing is the best! It is easily folded, stands sturdily, easy to assemble, and the fabric looks great. Very very happy with the quality for the price.

Arrived damaged
Color: Black, Size: 4 Panel Basic
Unfortunately, very cheaply made. It arrived with one of the connecting tubes cracked horizontally. Possibly due to bad welding. It is quite a headache to assemble. It was delivered on time but returned for a refund.

Not a great experience but a fine product
Color: Black, Size: 4 Panel Basic
not enough screws were included to make the wall. I was able to locate more screws to finish building-so I didn’t have to return the product- but it was a pain and I got lucky finding the pieces I needed but it could’ve been a fail and a returned product
