Overview
NF1 a Ras-GAP, highly expressed in developing neural cells. Possesses tumor suppressor activity, presumably by virtue of its GTPase activating domain. Neurofibromin is phosphorylated in response to EGF in CNS cells and cell lines. Defects in NF1 are the cause of type 1 neurofibromatosis (NF1), Watson syndrome, and familial spinal neurofibromatosis. NF1 is one of the most frequent autosomal dominant diseases. Four alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
