mtv, bks, brakeless, master of thickveins, l(2)04440
novel protein with a single zinc finger - multifunctional protein that regulates foraging activity and shapes the activity gradient of Dpp through regulation of thickveins - regulates transcription by interacting with Mediator complex subunit Med19

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).
Comment: maternally deposited
sbb transcripts are ubiquitously distributed in early embryos. After gastrulation, transcripts are observed in the developing central nervous system. Both major transcript types are observed in early embryose by RT-PCR.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

DNA-protein interactions: genome-wide binding profile assayed for sbb protein in 0-12 hr embryos; see mE1_TFBS_sbb collection report.
Mutant clones cause pattern defects in the adult wing, such as ectopic venation and transformation of bristle types.
sbb is essential for R1-R6 growth cone targeting.
sbb is required in the developing eye specifically for the lamina targeting of R1-R6 photoreceptor cell axons.
Larvae with mutations in sbb show abnormally high amounts of turning behaviour in the absence of food.
Mutant males court females and generate courtship songs with the normal pattern and yet are unsuccessful in copulation.

Mutant R1-R6 photoreceptor axons fail to stop in the lamina, which inspired the name "brakeless" (Y. Rao and S.L. Zipursky, personal communication).
Name reflects pattern of larval trail on agar plate.
