Gene Summary

Neurofibromin 1 (Nf1) encodes a protein that functions as a GTPase activating protein for the products of Ras85D and Ras64B in the larval and adult nervous system. Loss of Nf1 results in excess Ras-Raf-ERK signaling and to a non-cell-autonomous cAMP/PKA signaling defect. The product of Nf1 contributes to postembryonic growth, learning/memory, and circadian rhythm. [Date last reviewed: 2019-03-14] (FlyBase Gene Snapshot)

Additional Descriptive Data

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.

(Gouzi et al., 2011)

Nf1 protein is expressed in all post-mitotic neurons in the larval central nervous system, at all larval stages.

(Walker et al., 2006)

Nf1 protein is widely expressed in low amounts.

Additional comments

Other Comments

Nf1 mutant flies are defective in memory acquisition but not memory stability.

(Buchanan and Davis, 2010)

The reduced life span seen in Nf1 mutants is the product of the impairment of adenylyl cyclase/cAMP/PKA signalling.

(Tong et al., 2007)

Inactivation of Nf1 increases oxidative stress, mediated by downregulation of adenylyl cyclase/cAMP/PKA.

(Tong et al., 2007)

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.

(Inlow and Restifo, 2004)

dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R⁺ cell morphology.

(Kiger et al., 2003)

Nf1 has a role in circadian output via the Ras/MAPK signaling pathway.

(Williams et al., 2001)

Nf1 affects learning and short-term memory independently of its developmental effects.

(Guo et al., 2000)

Nf1 functions either upstream of adenylyl cyclase or in a parallel pathway.

(Bernards, 1998.11.6)

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.

(Bernards, 1998.11.6)

Activation of rut protein through heterotrimeric guanine nucleotide-binding protein-coupled receptor is regulated by Nf1.

(Guo et al., 1997)

Nf1 and Pka-C1 interact in a pathway that controls the overall growth of flies.

(The et al., 1997)

Nf1 is a crucial component for activation of the cAMP pathway.
