Gene Snapshot

crossveinless 2 (cv-2) encodes a secreted protein that binds BMPs, the BMP receptor encoded by tkv and Heparan Sulfate Proteoglycans. It either promotes BMP signaling, as in the developing crossveins, or inhibits BMP signaling, as in the early embryo. [Date last reviewed: 2019-03-07]

Additional Descriptive Data

cv-2 expression is first visible broadly around the crossveins and the end of the longitudinal veins at 21-22 hr APF. It becomes stronger and refines to a narrow stripe at 28-29 hr APF.

(Wagner et al., 2010)

cv-2 transcripts are most prominent near the anterior-posterior compartment boundaries in third instar imaginal discs, in the anterior and posterior crossveins in pupal wings and at the distal edges of longitudinal wing veins. Heightened expression is also observed in the dorsal regions of early embryos.

(Serpe et al., 2008)

Weak general expression is seen at all stages. In late third instar larvae, cv-2 transcripts are observed in three regions of the prospective notum. One contains and lies distal to the posterior notopleural bristle (pNP) and lies posterior to the anterior notopleural bristle (aNP). One lies distal to the trichoid sensillum (tri1). Transcripts are emphasized along the AP boundary of the prospective wing blade. In pupal wings at 19 hrs APF, transcripts are seen in broad regions around the crossveins. These resolve into narrower regions by 28 hr APF. Increased expression is also observed at the tips of the longitudinal veins.

cv-2 may act extracellularly or in the secretory pathway to directly potentiate dpp or gbb signalling in the crossvein.

(Conley et al., 2000)

Mutations in cv-2 remove transverse veins or crossveins: crossvein specific. Shows additive interactions with vn, ve, ci, cg, shv, ast, H, Vno, vvl, ri, tg, tt and ab.

(Diaz-Benjumea and Garcia-Bellido, 1990)

ri, tg, tt, ab, cv, cv-2, cv-c and cv-d belong to the radius incompletus phenotypic group within the 'lack-of-vein' mutant class. Loss-of-function alleles at these loci remove stretches of veins in two or more longitudinal veins. Double mutants of this group have additive phenotypes suggesting the genes are vein-specific, and have small lanceolate wings. Genes are involved in whole vein region-specification rather than vein differentiation.
