STEAP1B (STEAP Family Member 1B): STEAP1B, part of the Six Transmembrane Epithelial Antigen of the Prostate (STEAP) family, is involved in metalloreduction, particularly iron and copper reduction. It may play a role in cellular iron homeostasis and metabolism, which are vital for various physiological processes. The specific functions of STEAP1B in human health and disease are still being explored, with potential implications for understanding iron-related metabolic pathways....
