Q8MQJ9

Target Species

Drosophila melanogaster

Target Name

BRAT

Target Function

A NHL-domain family protein that functions a translational repressor to inhibit cell proliferation. Plays a central role in translation repression of hb mRNA by being recruited by nos and pum to the Nanos Response Element (NRE), a 16 bp sequence in the hb mRNA 3'-UTR. Probably recruited by other proteins to repress translation of other mRNAs in other tissues. Involved in the regulation of ribosomal RNA synthesis and cell growth. Participates in abdominal segmentation and imaginal disk development. During neuroblast division, segregates asymmetrically and inhibits self-renewal of one of the two daughter cells. Together with the asymmetrically segregating transcription factor prospero ensures that the daughter cell will stop growing, exit the cell cycle, and differentiate into neurons possibly by modulating the function of dm in ganglion mother cells (GMC). Restrics developmental potential of type II intermediary neuronal progenitor (INP) cells playing a role in proliferation and maturation of the neuroblasts.

Target Subcellular Location

Cytoplasm. Cytoplasm, cell cortex.

Target Tissue Specificity

Expressed during embryogenesis, mainly in nervous tissues. Expressed in the embryonic central and peripheral nervous systems including the embryonic brain. In third instar larva it is expressed in the larval central nervous system including the brain and
