(18) This gene, which encodes a transmembrane protein, is initially expressed in a generalized way at blastoderm, but later stops being transcribed in cells expressing the engrailed gene, and even later in cells in the middle of the parasegment.
(19) Autoregulation graduates to wingless independence, but is transient, and is superseded by an engrailed-independent mode of maintenance.
(20) It appears to control morphogenesis by regulating the expression of the segmentation gene engrailed (en), and by autoregulating its own expression (M. Frasch and M.L., in preparation).
Moth
Definition:
(n.) A mote.
(n.) Any nocturnal lepidopterous insect, or any not included among the butterflies; as, the luna moth; Io moth; hawk moth.
(n.) Any lepidopterous insect that feeds upon garments, grain, etc.; as, the clothes moth; grain moth; bee moth. See these terms under Clothes, Grain, etc.
(n.) Any one of various other insects that destroy woolen and fur goods, etc., esp. the larvae of several species of beetles of the genera Dermestes and Anthrenus. Carpet moths are often the larvae of Anthrenus. See Carpet beetle, under Carpet, Dermestes, Anthrenus.
(n.) Anything which gradually and silently eats, consumes, or wastes any other thing.

(5) The aetiology was established when patch tests with crude moth material produced similar eruptions in 5 out of 7 adult volunteers between 40 min and 12 h.
