Gene Summary
Ligand for the neuropeptide SIFamide receptor (PubMed:16378592). Modulates sexual behavior by negatively regulating female receptivity to male courtship and by playing a role in male sex discrimination (PubMed:17126293, PubMed:26469541). Also involved in promoting sleep (PubMed:24658384). (UniProt, Q6IGX9)

    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).

    Expression of SIFa was established via single cell RNA sequencing of Scer\GAL4Kurs58 or Scer\GAL4c767 positive pars intercerebralis neurons. Expression was found in two out of five tested cells.

    Additional Descriptive Data

    Expression of SIFa protein is found in a subset of four Scer\GAL4Kurs58 positive pars intercerebralis neurons.

    SIFa colocalizes with larval dorsomedial Scer\GAL4ATP7.PB expressing larval dorsomedial neurosecretory cells.

    SIFa protein is detected in layer 5 of the fan-shaped body, as well as faintly in the central and ventral layers.

    SIFa protein is expressed in 4 cells in the pars intercerebralis that extend processes throughout most of the brain neuropils, except for the mushroom body stalks, lobes and calyces. The processes that innervate the antennal lobe arborise in most glomeruli. In addition, 3 pairs of cell bodies are detected in the dorsolateral protocerebrum. The cells labelled in the pars intercerebralis by SIFa also express Scer\GAL4SIFa.PT.

    Ifa protein is expressed in two pairs of neurons in the pars intercerebralis, that project into the ventral nerve cord. These cells also have numerous Ifa varicosities in adult flies.

            Changed from 'IFa' to 'SIFa' to reflect usage in the literature and match nomenclature of the receptor ('SIFaR').

            Release 4.1 annotation CG33527 corresponds to the 3' part of release 2 annotation CG4681 (which was deleted in the release 3 version of CG4681). Release 4.1 annotation CG33527 corresponds to IFa.

            The 3' part of release 2 annotation CG4681 (which was deleted in the release 3 version of CG4681) corresponds to part of a separate gene - IFa.
