Detection of Human OASIS/CREB3L1 by Western Blot.
Western blot shows lysates of human brain tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human OASIS/CREB3L1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4080) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for OASIS/CREB3L1 at approximately 57 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

OASIS (old astrocyte specifically-induced substance) is a 57‑60 kDa member of the CREB/ATF family of transcription factors. Human OASIS is 519 amino acids (aa) in length. It is an ER transmembrane protein with a cytosolic N-terminus (aa 1‑374) and a luminal C‑terminus. The N-terminus contains one b-Zip region (aa 292‑353). Misfolded proteins in the ER induce proteolytic cleavage of OASIS. The released 66 kDa N-terminus translocates to the nucleus to activate stress response genes. There is one alternate splice form that shows a deletion of aa 112‑198. Over aa 1‑111, human OASIS shares 96% aa sequence identity with mouse OASIS.
