Tumor necrosis factor receptor member 16 trans-membrane domain This is the helical trans-membrane domain found in tumor necrosis factor receptor superfamily member 16 (also known as p75 neurotrophin receptor, and nerve growth factor receptor-NGFR). p75 plays prominent biological functions such the induction of cell death, and it demonstrates several other activities, like survival, axonal growth, and cell migration. The trans-membrane (TM) domain of p75 stabilizes the receptor dimers through a disulfide bond, essential for the NGF signalling Structural and mutational analysis indicate that Cys257 plays the key role in this stabilization process. Furthermore, although the p75-C257A mutant is still capable to form dimers and bind to NGF, it is unable to transduce the signals triggered by NGF binding in some cell signalling paradigms.
