Progesterone Receptor Membrane Component 1 (PGRMC1) is a small (~21-28 kDa), evolutionarily conserved protein with diverse cellular roles. Initially identified as a non-classical membrane-associated progesterone receptor, it belongs to the membrane-associated progesterone receptor (MAPR) family. Structurally, it contains a cytochrome b5-like heme-binding domain and a putative steroid-binding region. PGRMC1 is ubiquitously expressed in human tissues and localizes to the endoplasmic reticulum, plasma membrane, and nucleus.
Functionally, PGRMC1 interacts with proteins involved in cholesterol synthesis, drug metabolism (via cytochrome P450 enzymes), and cellular homeostasis. It regulates cell survival, proliferation, apoptosis, and autophagy, and plays roles in steroidogenesis, iron homeostasis, and vesicle trafficking. Its involvement in cancer progression, particularly in breast and ovarian cancers, has drawn significant attention, as overexpression correlates with chemotherapy resistance and poor prognosis. Emerging studies also link PGRMC1 to neurodegenerative diseases (e.g., Alzheimer’s) and reproductive physiology.
Recombinant human PGRMC1 is produced using bacterial or eukaryotic expression systems, enabling *in vitro* studies of its molecular interactions, signaling mechanisms, and therapeutic targeting. Its multifunctional nature and cross-talk with signaling pathways make it a compelling yet complex target for biomedical research.
