Recombinant Human CD271

Background

The nerve growth factor receptor (NGFR), also known as p75^NTR or CD271, is a receptor in the tumor necrosis factor receptor superfamily (TNFRSF) with critical roles in neuronal survival, differentiation, apoptosis, and regenerative processes. NGFR is primarily recognized for binding to nerve growth factor (NGF) but is also responsive to other neurotrophins, including brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4). NGFR serves as a high-affinity receptor, particularly in conjunction with Trk receptors and sortilin, with functions ranging from promoting neuronal survival to facilitating apoptosis, depending on the cellular context and ligand interaction. NGFR has diverse roles beyond the nervous system, including in immune regulation, inflammatory responses, and tissue repair. In non-neuronal tissues, NGFR is involved in cell survival, migration, and differentiation. Due to its versatile functions, NGFR is implicated in neurodegenerative diseases, peripheral neuropathy, and various cancers, including melanoma and glioblastoma, where it often contributes to tumor progression and resistance to apoptosis.
