  • Neurofibromatosis-related protein NF-1
Background InformationNeurofibromin (UniProt: P21359; also known as Neurofibromatosis-related protein NF-1) is encoded by the NF1 gene (Gene ID: 4763) in human and widely expressed in brain, peripheral nerves, lung, colon, breast, and muscle tissues. Germline NF1 loss-of-function mutations cause Neurofibromatosis type I. Somatic NF1 loss is also frequently detected in a wide range of tumors. Neurofibromin is a GTPase-activating protein (GAP) that negatively regulates RAS/MAK pathway by enhancing the hydrolysis of Ras-bound GTP. Its GAP domain is localized to amino acids 1235-1451. It also has a CRAL-TRIO domain (aa 1580-1738) that facilitates its binding to phospholipids. Neurofibromin has also been shown to serve as an estrogen receptor alpha (ER-a) transcriptional co-repressor through leucine/isoleucine-rich motifs, and this activity is independent of the GAP activity. Its depletion can thus cause estradiol hypersensitivity and tamoxifen agonism, which correlate with poor outcomes seen in ER+ breast cancer patients. Mutations in NF1 gene are known to cause Neurofibromatosis type I that involved tumors in the peripheral nervous system and fibromatous skin tumors. Some mutations are also known to cause colorectal cancer and juvenile leukemia. Six different isoforms of Neurofibromin have been described that are produced by alternative splicing.
