Background
Human Epidermal growth factor Receptor 2 (HER2) is also called ERBB2, HER-2, NEU, NGL, TKR1 and c-erb B2, and is a protein giving higher aggressiveness in breast cancers. It is a member of the ErbB protein family, more commonly known as the epidermal growth factor receptor family. HER2 protein cannot bind growth factors due to the lacking of ligand binding domain of its own and autoinhibited constitutively. However, HER2 forms a heterodimer with other ligand-bound EGF receptor family members, therefore stabilizes ligand binding and enhances kinase-mediated activation of downstream molecules. HER2 plays a key role in development, cell proliferation and differentiation. HER2 gene has been reported to associate with malignancy and a poor prognosis in numerous carcinomas, including breast, prostate, ovarian, lung cancers and so on.

Decent quality for the price and lots of space for your “stuff”.
Color: Single layer-Brown
This is a nice vanity tray for the price. There are a few minor rough edges but nothing that takes away from the overall appearance and functionality. This helps keep my dresser organized and holds a lot of items. I use this for my car keys, wallet, air pods, pocket knife, glasses, and a few bottles of cologne…and still have room to spare. Easy to recommend as a gift for a guy that has everything

Very nice
Color: Single layer-Brown
Dad needed something to help him remember the items he needs to take with him. So we purchased this organizer for him. He's been using it and makes sure it's empty before leaving the house. It has helped him tremendously. The only improvement I would recommend is make the box slot bigger for today's adult glasses.
