Summary: Involved in several processes, including digestive tract morphogenesis; proximal/distal axis specification; and spiracle morphogenesis, open tracheal system. Located in cytoplasm and nucleus. Is expressed in several structures, including embryonic epidermis; embryonic hindgut; inclusive hindgut primordium; mesoderm; and stomodeum. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder 27. Orthologous to human LINS1 (lines homolog 1).

What's a GeneRIF?

Lines acts antagonistically to bowl in hub specification, establishing bowl as a positively acting factor in the development of the testis niche.
Title: lines and bowl affect the specification of cyst stem cells and niche cells in the Drosophila testis.
by preventing Bowl accumulation in the wing, primordial Lines permits the correct balance of nuclear co-repressors that control the activity of the Wingless, Notch and Hedgehog pathways
Title: Lines is required for normal operation of Wingless, Hedgehog and Notch pathways during wing development.
Here we show that Lines accumulates in nuclei in the presumptive tarsus and the inter-joints of proximal leg segments and governs the formation of these structures by destabilizing the nuclear protein Bowl
Title: Essential roles for lines in mediating leg and antennal proximodistal patterning and generating a stable Notch signaling interface at segment borders.
Reciprocal roles are reported for bowl and lin in specifying the peripodial epithelum and the disc proper of the wing.
Title: Reciprocal roles for bowl and lines in specifying the peripodial epithelium and the disc proper of the Drosophila wing primordium.
Drm and Lines regulate Bowl protein accumulation and consequent patterning in the epithelia of the foregut, hindgut, and imaginal discs.
Title: The Drumstick/Lines/Bowl regulatory pathway links antagonistic Hedgehog and Wingless signaling inputs to epidermal cell differentiation.
data show that drm encodes a zinc finger protein that is a member of the Odd-skipped family. drm expression is localized to the developing midgut-hindgut junction, while lines is broadly expressed throughout the gut primordium
Title: Drumstick is a zinc finger protein that antagonizes Lines to control patterning and morphogenesis of the Drosophila hindgut.
