Insertion lines from this collection were assessed for inclusion in the Gene Disruption Project collection.
In embryonic tracheal system: expressed in a highly restricted, dispersed set of cells; each of these cells migrates toward and contacts a similar expressing cell in the neighboring tracheal hemisegment and mediates a fusion event.
l(2)07769
This insertion was listed in the BDGP database as a lethal or sterile line during the period 1994-1999, but was not verified as such prior to the summary publication (FBrf0111489). Reasons for excluding lines from the collection described in FBrf0111489 include presence of more than one P insertion on the mutant chromosome, separation of lethality (or sterility) from the location of the insertion, and loss of lethality (or sterility) from the stock.
