This biomarker is also known as:
  • transport protein SEC23B,
  • protein transport protein Sec23B,
  • CDAII,
  • SEC23-like protein B,
  • congenital dyserythropoietic anemia, type II,
  • CDAN2,
  • Sec23 (S. cerevisiae) homolog B,
  • Q15437,
  • CDA-II,
  • SEC23-related protein B,
  • Sec23 homolog B (S. cerevisiae),


SEC23B is a member of the SEC23B/SEC24B family. SEC23B is a component of the COPII coat, that covers ER-derived vesicles involved in transport from the endoplasmic reticulum to the Golgi apparatus. By similarity, it has been shown that COPII acts in the cytoplasm to promote the transport of secretory, plasma membrane, and vacuolar proteins from the endoplasmic reticulum to the Golgi complex.

Performance Comment

SEC23B was one of 50 tumor vasculature-associated genes with transmembrane or secreted protein products identified through expression profiling of ovarian cancer vascular cells. These 50 tumor vascular markers (TVMs) also had low or no expression in normal tissues. SEC23B was not in the group of 13 selected for further validation.
