Overview

In flies, hemocyte-specific expression of an activated form of RAS (Dmel\Ras85DV12) in combination with knockdown of either scrib or l(2)gl results in dramatic increases in hemocyte number (in the range of 100-fold). The animals typically die during the larval or pupal stage. Phenotypes reminiscent of cachexia are observed. Responses to infectious agents have been assessed.

The constitutively active Ras85D mutation, Ras85DV12, is analogous to oncogenic mutations found in human RAS proteins. Variant(s) implicated in human disease tested (as analogous mutation in fly gene): G12V in the fly Ras85D gene (corresponds to G12V in the human KRAS and HRAS genes).

The Scribble polarity complex plays a key role in determining cell polarity and cell proliferation in epithelial cells. Classical amorphic and hypomorphic mutations, RNAi-targeting constructs, and alleles caused by insertional mutagenesis have been generated for both scrib and l(2)gl.

Drosophila cancer models using Ras85DV12 and genes encoding components of the Scribble complex have been developed using epithelial systems. See 'cancer, epithelial, RAS-LLGL-related' (FBhh0000588) and 'cancer, epithelial, RAS-SCRIB-related' (FBhh0000585).

      Gene Snapshot
      Ras oncogene at 85D (Ras85D) encodes a protein that acts downstream of several cell signals, most notably from Receptor Tyrosine Kinases, to regulate tissue growth and development. When abnormally activated it can direct developmental defects and tissue hyperplasia, mimicking aspects of human disease including Rasopathies and cancer, respectively.

      Comments on ortholog(s)

      High-scoring ortholog of human genes KRAS, HRAS, and NRAS (many to many; multiple paralogs and orthologs in both species). Dmel\Ras85D shares 78-86% identity and 86-92% similarity with KRAS, HRAS, and NRAS; for these three human genes, Ras85D is the highest-scoring ortholog in Drosophila.

      Gene Snapshot
      scribble (scrib) encodes a scaffolding protein that is part of the conserved machinery regulating apicobasal polarity. It acts with the products of dlg1 and l(2)gl to distinguish the basolateral domain of epithelial cells and neuroblasts, via reciprocally antagonistic interactions with the aPKC/par-6 complex that impacts vesicle trafficking. The product of scrib also organizes synaptic architecture and is implicated in learning and memory. [Date last reviewed: 2019-03-14]
      Gene Groups / Pathways
      Comments on ortholog(s)

      Ortholog of human SCRIB and LRRC1 (1 Drosophila to 2 human); Dmel\scrib shares 33% identity and 45% similarity with the human SCRIB gene. The human LRRC1 gene encodes a much smaller protein, corresponding to the amino end of SCRIB and Dmel\scrib; it shares 57% identity and 73% similarity with Dmel\scrib within that extent.

      Gene Snapshot
      lethal (2) giant larvae (l(2)gl) encodes a tumor suppressor protein that regulates cell polarity and asymmetric cell division. It acts on the basolateral side of epithelial cells, antagonizing the activity of apical complex proteins encoded by baz, par-6 and aPKC. [Date last reviewed: 2019-09-26]
      Gene Groups / Pathways
      Comments on ortholog(s)

      Moderate- to high-scoring ortholog of human LLGL1 and LLGL2 (1 Drosophila to 2 human). Dmel\l(2)gl shares 34-36% identity and 51-54% similarity with the human genes.
