Gene Group (FlyBase)
RHOMBOID PROTEASES -
Rhomboid proteases are intramembrane serine proteases related to rho, that cleave other transmembrane proteins within their transmembrane domains. Rhomboid proteases are best characterized for their role in epidermal growth factor signaling, where they are required for the production the soluble, secreted ligand. (Adapted from FBrf0235672). Rhomboid proteases are intramembrane serine proteases related to rho, that cleave other transmembrane proteins within their transmembrane domains. Rhomboid proteases are best characterized for their role in epidermal growth factor signaling, where they are required for the production the soluble, secreted ligand. They belong to MEROPS family S54. (Adapted from FBrf0235672).
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
ru: roughoid
Eyes small and rough, have irregular facets and hairs, and have black specks from erupted facets. Expression variable; sometimes overlaps wild type. SEM study by Stumm-Tegethoff and Dick (1974, Theor. Appl. Genet. 44: 262-65).
Summary (Interactive Fly)

intra-membrane serine protease localized in the endoplasmic reticulum - Rhomboid and Roughoid/Rhomboid-3 act together on an unknown Egf to control cell recruitment through the Epidermal growth factor receptor most notably the eye

        Additional comments
        Other Comments

        ru protein cleaves S within its transmembrane domain.

        ru, expressed in the ventral nerve cord, is necessary for repulsion of ganglionic tracheal branches from the ventral midline.

        ru regulates Egfr signalling in the eye.

        The abnormal ru phenotype is due to a developmental defect: late occurring defects. Adult eyes rough and reduced, with photoreceptor and pigment cell defects, eye disc pattern appears normal.
