CC -!- FUNCTION: Required for visual system development. May transcriptionally
CC regulate genes necessary for optic lobe invagination and Bolwig's nerve
CC formation. {ECO:0000269|PubMed:7896096, ECO:0000269|PubMed:7910468}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00108,
CC ECO:0000269|PubMed:7910468}.
CC -!- TISSUE SPECIFICITY: In developing embryos, expressed in the eye disk
CC epithelium, bolwig's organ and the optic lobe primordium at areas of
CC invagination. In adults, present in photoreceptor cells in the apical
CC regions of the retina, and in optic lobes.
CC {ECO:0000269|PubMed:7910468}.
CC -!- DEVELOPMENTAL STAGE: In the eye imaginal disk, first expressed at the
CC onset of the third instar and continues throughout this stage.
CC Expression in the optic lobe primordium begins at stage 5 and
CC disappears when invagination is completed (stage 12). Further
CC expression is noted in optic lobe ganglia in late third instar.
CC {ECO:0000269|PubMed:7910468}.
CC -!- DISRUPTION PHENOTYPE: Flies specifically display visual defects. These
CC range from reduced ocelli and ommatidia number in weak loss-of-function
CC phenotypes to complete absence of compound eyes and bolwig's organ in
CC more severe lethal phenotypes. {ECO:0000269|PubMed:7896096,
CC ECO:0000269|PubMed:7910468}.
CC -!- SIMILARITY: Belongs to the SIX/Sine oculis homeobox family.
CC {ECO:0000305}.
