Gene Summary
Myoinhibiting peptide precursor (Mip) encodes a member of the allatostatin family of peptides - specifically, the B-type allatostatins. Mip can act as a neuropeptide, neurohormone, and/or a hormone to regulate the nervous system and metabolic processes. [Date last reviewed: 2023-09-07] (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)
    Ligand for the sex peptide receptor (SPR) (PubMed:20308537, PubMed:20458515, PubMed:25333796). Stabilizes sleep and maintains sleep homeostasis to inhibit the activity of wake-promoting circuits, such as those that involve the pigment dispersing factor (pdf) neurons. Regulated by the circadian clock network and pathways associated with a sleep homeostat (PubMed:25333796). May also have a regulatory role in gut motility (PubMed:11181081).
    (UniProt, Q9VVF7)
    Summary (Interactive Fly)

    ancestral ligand for the Sex peptide receptor - acts directly in the polyamine-detecting olfactory and taste neurons - regulation of polyamine attraction, stabilization of sleep

    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).

    Mip transcript is co-expressed with Mip protein in 52 neurons of the adult brain.

    Mip is expressed in one cell in the midline of the mandibular segment and one cell in the midline of the labial segment that was identified as VUM interneuron 1 (iVUM4 in paper).

    Additional Descriptive Data

    Mip protein is expressed in around 70 neurons of the adult brain innervating the adult antennal lobe and subesophageal zone.

    Mip protein is detected in most layers of the fan-shaped body, which the authors identify as layers 2-7, in a columnar organisation. The strongest staining is observed in layer 5, where it co-localises with ScerGAL4c205. Co-localisation with ScerGAL4Cha.7.4 is detected in a group of 4 neurons in the dorsolateral protocerebrum and their projections in the fan-shaped body.

    Mip peptides were detected in extracts from adult and larval midguts.

    Mip protein is expressed in 10-15 local neurons that innervate most adult antennal lobe glomeruli. These neurons have their cell bodies in one lateral cluster. Four to five of these neurons co-express ScerGAL4Cha.7.4.

    Strong immunoreactivity was observed in the adult CNS but not in male reproductive organs.

    Mip is expressed in a group of 7-30 large endocrine cells in the larval anterior midgut in a region just before the copper cells of the middle midgut. It is also expressed in up to 20 smaller cells in the copper cell region that tend to more numerous at the posterior end of the middle midgut. It is also expressed in a group of cells in the anterior region of the posterior midgut
