It interacts with key cellular regulators such as Ran-binding-protein-5 and protein-phosphatase-2A, and appears to influence signaling through novel neurotrophin pathways including those mediated by NNT1 and p48ZnF. Its down-regulation in Alzheimer’s disease brains suggests that p60TRP—as a GPCR-associated sorting protein (GPRASP3)—may be pivotal for maintaining the balance between cell survival and programmed cell death in neural tissues."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}, {"type": "p", "children": [{"type": "t", "text": "\nIn addition to its neuroprotective functions, p60TRP (GPRASP3) has been implicated in cancer biology.
