NCBI Summary for NF1
This gene product appears to function as a negative regulator of the ras signal transduction pathway. Mutations in this gene have been linked to neurofibromatosis type 1, juvenile myelomonocytic leukemia and Watson syndrome. The mRNA for this gene is subject to RNA editing (CGA>UGA->Arg1306Term) resulting in premature translation termination. Alternatively spliced transcript variants encoding different isoforms have also been described for this gene. [provided by RefSeq, Jul 2008]
UniProt Comments for NF1
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.
