Immunogen

Synthetic peptide directed towards the N terminal region of human STIP1

Application

Anti-STIP1 (AB1) antibody produced in rabbit can be used to tag stress-induced-phosphoprotein 1 (Hsp70/Hsp90-organizing protein) for detection and quantitation by using western blotting at a concentration of 1.25μg/ml.

Biochem/physiol Actions

Stress-induced-phosphoprotein 1 (STIP1) also referred to as Hsp70/Hsp90-organizing protein, HOP, STI1, STI1L or P60 is a co-chaperone that regulates and assists heat shock proteins (major chaperones). STIP1 facilitates the interaction of chaperones Hsp70 and Hsp90 for proper protein folding. Additionally, it assists as a novel biomarker for ovarian cancer. STIP1 secreted by human ovarian cancer cells binds to a bone morphogenetic protein (BMP) receptor, ALK2 (activin A receptor, type II-like kinase 2) and activates SMAD-ID3 signaling pathways. Hence, STIP1-ALK2 pathway promotes cell proliferation in ovarian cancer cells.

We previously identified Hop as over expressed in invasive pancreatic cancer cell lines and malignant tissues of pancreatic cancer patients, suggesting an important role for Hop in the biology of invasive pancreatic cancer. Hop is a co-chaperone protein that binds

Stress-induced phosphoprotein 1 (STIP1), a cochaperone that organizes other chaperones, heat shock proteins (HSPs), was recently shown to be secreted by human ovarian cancer cells. In neuronal tissues, binding to prion protein was required for STIP1 to activate the ERK

Factors released by glioma-associated microglia/macrophages (GAMs) play an important role in the growth and infiltration of tumors. We have previously demonstrated that the co-chaperone stress-inducible protein 1 (STI1) secreted by microglia promotes proliferation and migration of human glioblastoma (GBM) cell
