ITM2A Antibody

Western Blot shows lysates of A‑673 human Ewing's sarcoma cell line. PVDF membrane was probed with 2 µg/ml of Sheep Anti-Human ITM2A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4876) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for ITM2A at approximately 39 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background

ITM2A (Integral membrane protein 2A; also protein E25) is a 43-45 kDa member of the ITM2 family of proteins. It is expressed by chondrocytes involved in endochondrial ossification, skeletal muscle, adipose tissue-derived stem cells, and CD3-activated CD4⁺ and CD8⁺ T cells. ITM2A is found embedded in both plasma membrane and Golgi complex. Human ITM2A is a 263 amino acid (aa) type II transmembrane glycoprotein. The ECD (aa 75-263) contains one BRICHOS domain (aa 133‑227). Proteolytic cleavage by furin is typical for BRICHOS domain-containing proteins. ITM2A may exist as a dimer. There are two potential splice variants, one that shows a deletion of aa 55-81, and a second that shows a deletion of aa 38-81. Full-length human ITM2A shares 95% aa identity with mouse ITM2A.
