Nf1 is expressed in most, if not all, cell body regions of the adult central brain. Expression is apparent in cell body regions surrounding the antennal lobes, protocerebrum, lateral horn and the mushroom body calyces.
Nf1 protein is expressed throughout the third instar larval and adult brain. In the adult, labelling is stronger in the mushroom body calyx and cortex (dendrites and cell bodies of Kenyon cells, respectively), protocerebral bridge, subesophageal ganglion and median bundle. Expression of Nf1 protein in the protocerebral bridge and mushroom body calyx colocalises with that of Alk protein.
Nf1 protein is expressed in all post-mitotic neurons in the larval central nervous system, at all larval stages.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
Nf1 mutant flies are defective in memory acquisition but not memory stability.
The reduced life span seen in Nf1 mutants is the product of the impairment of adenylyl cyclase/cAMP/PKA signalling.
Inactivation of Nf1 increases oxidative stress, mediated by downregulation of adenylyl cyclase/cAMP/PKA.
One of 42 Drosophila genes identified as being most likely to reveal molecular and cellular mechanisms of nervous system development or plasticity relevant to human Mental Retardation disorders.
dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
Nf1 affects learning and short-term memory independently of its developmental effects.
Nf1 deficient phenotypes (reduced size, absence of a PACAP-induced rectifying potassium current at the larval neuromuscular junction) are not modified by manipulating Ras85D or Ras64B gene dosage, but rather are rescued by increasing signaling through the cAMP - PKA pathway.
