Anti-Sec23B Antibody

The protein named Sec23B, also known as protein transport protein Sec23B, or SEC23-related protein B is a component of the COPII coat, the complex that governs ER-derived vesicles involved in transport from the endoplasmic reticulum to the Golgi apparatus. The transport of proteins in eukaryotic cells from the endoplasmic reticulum (ER) to the Golgi complex proceeds by deformation of specialized portions of the donor membrane to form carrier vesicles. A group of cytosolic proteins collectively known as COPII carry out a programmed set of sequential interactions, leading to cargo sorting and vesicle budding. The Sec23B protein is critical to proper protein transport in and out of cells, and it is localized to the smooth endoplasmic reticulum membrane where it is a peripheral membrane protein and interacts with the Golgi apparatus membranes as well. Sec23B is expressed at high levels in brain and fibroblasts as well as liver and other metabolically active tissues. Defects in Sec23B cause congenital dyserythropoietic anemia type II, a recessive disorder of erythroid differentiation but the disease is not caused by loss of function of Sec23B but rather a combination of a hypomorphic allele with altered functionality appears to be the cause and its related protein Sec23A can often compensate somewhat for the defect.

Western Blotting Analysis: A representative lot from an independent laboratory detected Sec23B in various mouse tissue lysates expressing wild-type Sec23B. The same lot detected Sec23B in Sec23B wild-type MEF cell lysates and demonstrated a loss of signal in Sec23B knockdown MEF cell lysates (Tao, J., et al. (2012). Proc Natl Acad Sci USA. 109(29):E2001-E2009.).

Affinity purified

Purified rabbit polyclonal in buffer containing 0.1 M Tris-Glycine (pH 7.4), 150 mM NaCl with 0.05% sodium azide.

Stable for 1 year at 2-8°C from date of receipt.

Evaluated by Western Blotting in mouse pancreas tissue lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected Sec23B in 10 µg of mouse pancreas tissue lysate.
