Background

Human Siglec-2, also known as B cell antigen CD22 or B lymphocyte cell adhesion molecule (BL-CAM), is a B cell restrictive glycoprotein that is expressed in the cytoplasm of progenitor B and pre-B cells and on the surface of mature B cells. CD22 mediates the interaction between B cells and may participate in the localization of B cells in lymphoid tissue. Siglec-2/CD22 binds to sialylated glycoproteins and plays a role in positive regulation by interacting with the Src family tyrosine kinases. It may also act as an inhibitory receptor by recruiting cytoplasmic phosphatase through its SH2 domain, blocking signal transduction through dephosphorylation of signaling molecules.

Great item!

These shelves were great! I put them in the bathroom and helped with added space for holding candle and items to help keep counter clear.

Good quality
Color: Dark Walnut, Size: 11.2inch(2PCS)
These were the perfect fit, and they came with all the necessary hardware. We like them so much that we bought a different size for another room in our house, and they were perfect as well. They are a very nice quality wood. It's not that cheap stuff that will fall apart.
