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

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

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).

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.
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.
Comment: expression assayed in cultured cells
Comment: not expressed until late embryonic stage 16

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
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.
