Gene Group Membership
C2H2 ZINC FINGER TRANSCRIPTION FACTORS -
Zinc finger C2H2 transcription factors are sequence-specific DNA binding proteins that regulate transcription. They possess DNA-binding domains that are formed from repeated Cys2His2 zinc finger motifs. (Adapted from PMID:1835093, FBrf0220103 and FBrf0155739).
Negative Regulators of JAK-STAT Signaling Pathway -
Negative regulators of JAK-STAT signaling down-regulate the pathway, attenuating transcriptional control by Stat92E.
UniProt Contributed Function Data
Transcription factor required for terminalia development. Negative regulator of the JAK/STAT pathway: represses JAK/STAT-dependent expression of ventral veins lacking (vvl) in the posterior spiracles.

Additional Descriptive Data
Northern analysis indicates that expression of ken is higher during embryonic and pupal stages than in larval stages. Expression of ken is higher in adult females than in males. ken transcript is expressed ubiquitously in both male and female genital discs and eye-antennal discs. In the embryo ken transcript is detected in stage 5 blastoderm embryos as 2 stripes at 64% and 17% egg length. Expression is stronger with the anterior expression just posterior to the cephalic furrow and posterior expression confined to the hindgut primordium. Anterior expression disappears by stage 9 and then reappears in the foregut at stage 15. Posterior expression is confined to the hindgut and anal pad.
ken transcripts are first detected in early stage 5 embryos in two circumferential rings around the embryo at 17% and 64% egg length. At the end of stage 5, they co-localize with the first and seventh ftz stripes. The anterior stripe fades while the staining in the posterior domain persists until the end of embyrogenesis in the posterior spiracles. Expression is also observed at stage 16 in the foregut, the proventriculus, the dorsal pouch, the hindgut, and the anal pads.
