补充信息

STEAP1 also known as Six Transmembrane Epithelial Antigen of the Prostate 1 is a plasma membrane protein with a molecular weight around 50 kDa. This protein is expressed primarily in prostate tissues but also in a variety of other epithelial tissues. It plays a mechanical role as a metalloreductase facilitating the reduction of metal ions such as iron and copper across the cell membrane. STEAP1 features a characteristic six transmembrane domain which is important for its activity and localization.

Biological function summary

STEAP1 impacts cellular processes connected to metal ion homeostasis and proliferation. By performing as a metalloreductase it modulates the redox state and availability of metal ions within cells. STEAP1 functions as part of a larger complex interacting with other transmembrane proteins in the regulation of ion transport and reduction reactions. These roles are significant in maintaining cellular metabolism and oxidative balance.

Pathways

STEAP1 is actively involved in pathways related to iron and copper metabolism. It links to the iron uptake and transport pathways ensuring proper cellular iron levels are maintained. STEAP1 also shares functional relationships with proteins such as ferritin which stores iron and transferrin which transports iron in the bloodstream. STEAP1 therefore plays an important part in connecting cellular metabolism to systemic metal homeostasis.

STEAP1 has notable associations with prostate cancer and Ewing's sarcoma. Elevated expression of STEAP1 often correlates with the progression of prostate cancer hinting at a potential role in tumor growth and survival. In Ewing's sarcoma STEAP1 engages in molecular mechanisms related to the disease's pathology. Interaction with proteins such as PCA3 a prostate cancer antigen underlines its involvement in carcinogenic processes and highlights its potential as a therapeutic target in oncology.

靶点信息

Does not function as a metalloreductase due to the absence of binding sites for the electron-donating substrate NADPH. Promotes Fe(3+) reduction when fused to the NADPH-binding domain of STEAP4.
