Gene Snapshot
Rap1 GTPase (Rap1) encodes a small GTPase in the Ras superfamily. When GTP bound, it binds to a number of different effectors, one of which is the product of scno. Together they regulate many morphogenetic movements including mesoderm invagination and dorsal closure, help establish apical-basal polarity during cellularization, regulate macrophage migration, help define neuroblast asymmetric division, and play a role in planar cell polarity in the imaginal discs.

Gene Group (FlyBase)
RAS GTPASES -
The Ras family are members of the Ras superfamily of small GTPases. Ras proteins act in signal transduction cascades, generally the activated GTPase recruits and activates downstream effectors. Members this family are typically membrane-associated via isoprenylation of a CaaX motif in the C-terminus. (Adapted from PMID:15731001).
Pathway (FlyBase)
Torso Signaling Pathway Core Components -
The formation of Drosophila embryonic termini is controlled by the localized activation of Torso (tor) receptor tyrosine kinase. The Torso signaling pathway acts via the canonical Ras/Raf/MAP kinase cascade. (Adapted from FBrf0157176.)
Positive Regulators of Sevenless Signaling Pathway -
Positive regulators of Sevenless signaling up-regulate the pathway, promoting cell fate to that of an R7 photoreceptor. (Adapted from FBrf0127283 and FBrf0221727).
Positive Regulators of Hedgehog Signaling Pathway -
Positive regulators of hedgehog signaling down-regulation the pathway, enhancing the activation of transcription of hh-responsive genes.
Negative Regulators of Hippo Signaling Pathway -
The Hippo signaling pathway is an intracellular kinase cascade in which hpo kinase in complex with sav, phosphorylates wts kinase which, in turn, phosphorylates yki transcriptional co-activator leading to its cytosolic retention. Negative regulators of the pathway promote the nuclear accumulation of yki, enhancing yki-mediated transcriptional regulation and the expression of genes that positively regulate tissue growth (Adapted from FBrf0224870).
Protein Function (UniProtKB)
Ras proteins bind GDP/GTP and possess intrinsic GTPase activity. Plays a role in photoreceptor cell determination. ACTIVITY REGULATION: Alternates between an inactive form bound to GDP and an active form bound to GTP. Activated by a guanine nucleotide-exchange factor (GEF) and inactivated by a GTPase-activating protein (GAP).
(UniProt, P08645)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
R: Roughened
Eyes of R/+ rough, have some large dark facets. Photoreceptor cell 7 frequently absent (Carthew). Male genitalia frequently rotated and male sometimes sterile; viability about 80% wild type. Homozygote semilethal; wings spread. Thorax short; acrostichal hairs deranged, some missing; eyes small. Homozygous female fertile. RK1.
*R51b
Eyes of heterozygote small, oblong, and rough; facets and eye hairs irregular. Viability good. Homozygote lethal. R51b/R has very small eyes, much fusion of facets, and resembles gl and Gl. RK1.
Summary (Interactive Fly)

Ras-like GTPase - establishes of cell polarity by regulation of columnar cell shape - controls epithelial invagination via α-Catenin - regulates cell morphology within the developing wing epithelium - regulates radial movement of mesodermal cells during monolayer formation - regulates adhesive contacts necessary for maintenance of Egfr signaling between cells and differentiation of wing veins and photoreceptors

        Additional comments

        Renamed from 'R' to 'Rap1' to represent community usage and to minimise confusion with the 'r' ('rudimentary') gene symbol, from which it differed only by case.

        Other Comments

        R is required for macrophage shape and migration during embryogenesis.

        R and cno proteins act in the same molecular pathway during dorsal closure and the function of both proteins in dorsal closure depends on their ability to interact with each other. R acts upstream of cno in dorsal closure, but unlike cno, is not involved in the stimulation of JNK pathway activity.

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

        RNAi screen using dsRNA made from templates generated with primers directed against this gene causes a phenotype when assayed in Kc167 and S2R+ cells: cells become round and detached.

        Cells mutant for R condense their adherens junctions to one side of the cell in clones in the wing. This disrupts normal epithelial cell behaviour, leading to the mutant cell clones dispersing into the surrounding wild-type tissue.

        Ras85D-mediated signalling pathways are not influenced by R levels. Ras85D and R seem to function via distinct pathways. R has a regulatory role in morphogenesis in the eye, ovary and embryo. R also plays a role cell migration and cell shaping.

        Candidate gene for quantitative trait locus.

        Analysis of genetic interactions among faf and R and Ras85D reveals that in addition to its critical role anterior to the morphogenetic furrow, faf has a function in undifferentiated cells alter in eye development that involves, probably indirectly, Ras85D and R. These results suggest that cells outside the facet influence cell fates within the facet.

        R is essential for cell proliferation although it is not required for cell survival in post-mitotic cells. It is also required during oogenesis.

        R mutations disrupt the normal cell fate specification in photoreceptor cells.

        The transcription pattern of R was analyzed in neuroblasts derived from tumorous larval brain of l(2)gl larvae and S2 tissue culture cells. R expresses constitutive as well as maternal/embryonic-specific transcripts.

        An unusually low recovery rate of certain classes of deletions for the R locus suggests that a chromosome interval within 62B3-4 to 62D3-4 may be dominantly sensitive to position effects.

        Isolated as a Ras homologue, but also found to share high homology with human Rap.
