Gene Summary
locomotion defects (loco) encodes a regulator of G-protein signalling protein. loco product functions in neuroblast asymmetric division and blood-brain barrier formation together with G protein-coupled receptors and inhibitory G-proteins (encoded by Gαi and Gαo). It is also known that decrease of loco expression extends lifespan with stronger resistance to stressors. [Date last reviewed: 2018-10-04] (FlyBase Gene Snapshot)

Gene Snapshot
locomotion defects (loco) encodes a regulator of G-protein signalling protein. loco product functions in neuroblast asymmetric division and blood-brain barrier formation together with G protein-coupled receptors and inhibitory G-proteins (encoded by Gαi and Gαo). It is also known that decrease of loco expression extends lifespan with stronger resistance to stressors. [Date last reviewed: 2018-10-04]
Protein Function (UniProtKB)
Acts as a regulator of G protein signaling (RGS). Modulates G protein alpha subunits nucleotide exchange and hydrolysis activities by functioning either as a GTPase-activating protein (GAP), thereby driving G protein alpha subunits into their inactive GDP-bound form, or as a GDP-dissociation inhibitor (GDI). Confers GDI and GAP activities on G(i) alpha subunit Galphai. Confers GAP activity on G(o) alpha subunit Galphao and G(i) alpha subunit Galphai. Involved in the dorsal-ventral axis formation of the egg. Acts as a G-protein signaling for glial cell differentiation during embryogenesis; Galphai, Galphao and the G-protein coupled receptor, moody, are required in the surface glia to achieve effective insulation of the nerve cord. May be essential for nurse cell dumping during oogenesis. Required in neuroblast asymmetrical cell division. Plays a role in stress resistance and life span control.
(UniProt, Q9VCX1)
Summary (Interactive Fly)

regulators of G-protein signalling (RGS) protein - a GTPase-activating protein (GAP) acting on alpha subunit of G-proteins - Mutant glial cells fail to properly ensheath longitudinal axon tracts and do not form the normal glial-glial cell contacts, resulting in a disruption of the blood-brain barrier

Additional Descriptive Data

loco "c2" transcripts are observed in scattered cells in the lateral ectoderm that may correspond to PNS progenitor cells.

loco "c1" transcripts are detected only weakly. They are first detected in stage 12 embryos. By stage 16, they are detected in glial cells, in dorsal leading edge cells in the lateral ectoderm, and in tracheal cells.

Additional Descriptive Data

fzr protein and loco protein are strongly co-localized along the ventral edge of the larval brain near the margin between the brain and ventral ganglion but not in deeper regions of the brain. Both proteins are expressed within glial cells and are also expressed early in neuroblasts in third instar larvae.

Other Comments

Embryos transfected with dsRNA made from templates generated with primers directed against this gene show defects in the formation of the blood-brain barrier. The hatching rate of embryos transfected with loco dsRNA is much lower than controls and locomotor behaviour of larvae that do hatch is often severely impaired.

Identified with:GH08607

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

Shows particularly robust cycling of transcription in adult heads, as assessed by expression analysis using high density oligonucleotide arrays with probe generated during three 12-point time course experiments over the course of 6 days. Shows significant change of expression pattern in circadian mutant background; decreased expression in per01, tim01 and ClkJrk background.

loco is required for dorsal ventral axis formation of the egg and embryo and nurse cell dumping.

loco is required for glial differentiation.

loco mutant embryos show a severe glial cell differentiation defect.

Identification: Enhancer-trap technique to analyse possible glial specific target genes of pnt has identified loco.

Enhancer trap technique to analyse glia-specific target genes of pnt has identified loco.
