Gene Summary
neuropeptide F (NPF) encodes a 36-residue amidated peptide that signals through its receptor NPFR activating an inhibitory G-protein. Major functions of NPF signaling include the regulation of feeding and courtship behavior, metabolism, alcohol sensitivity, aggression as well as learning and memory. It further plays a role in the regulation of circadian behavior, in particular by modifying evening activity and free-running period. [Date last reviewed: 2019-03-14] (FlyBase Gene Snapshot)

    Gene Group (FlyBase)
    NEUROPEPTIDES -
    Neuropeptides are secreted into the extracellular space where they interact with cell surface receptors (usually G protein coupled receptors). They are extremely diverse, acting as neurotransmitters, neuromodulators, hormones or growth factors. (Adapted from FBrf0211443 and PMID:27813667).
    Protein Function (UniProtKB)
    Integral part of the sensory system that mediates food signaling, providing the neural basis for the regulation of food response; coordinates larval foraging and social behavior changes during development. Required in dopaminergic (DA) neurons that innervate the mushroom body for satiety to suppress appetitive memory performance; a key factor in the internal state of hunger in the brain. NPF neurons coordinately modulate diverse sensory and motor neurons important for feeding, flight, and locomotion. NPF/NPFR pathway exerts its suppressive effect on larval aversion to diverse stressful stimuli (chemical stress and noxious heat) through attenuation of TRP channel-induced neuronal excitation. NPF neural signaling system plays a physiological role in acute modulation of alcohol sensitivity in adults, rather than a general response to intoxication by sedative agents. Activation and inhibition of the NPF system reduces and enhances ethanol preference, respectively. Sexual experience, the NPF system activity and ethanol consumption are all linked; sexual deprivation is a major contributor to enhanced ethanol preference.

    Model Confidence:
    • Very high (pLDDT > 90)
    • Confident (90 > pLDDT > 70)
    • Low (70 > pLDDT > 50)
    • Very low (pLDDT < 50)

    AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

    Testis-specificity index

    The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

    NPF is expressed in 7 tachykinin neurons in the anterior ventrolateral protocerebrum labelled by ScerGAL4Tk

    NPF protein labels some of the clock neurons, including, in males, three LNd neurons, three or four l-LNv neurons (weaker signal) and the Pdf negative s-LNV neuron. Females express NPF protein in one less LNd and l-LNv neurons on average than males. Labelling was strongly detected in other non-clock cells in the central and lateral brain, including in the fan-shaped body. The expression pattern is similar to that of ScerGAL4npf.1, except that varicosities and axon terminals are more strongly stained with NPF protein.

    NPF protein is detected in a dorsal and ventral layers of the fan-shaped body.

    NPF protein is detected in neurons whose cell bodies are in the subesophageal ganglion. These neurons are not labelled by ScerGAL4npf.1. NPF protein is also detected in the dorsal and lateral protocerebrum, and fan-shaped body.
