The process during which the R3/R4 photoreceptors commit to their cell fate. R3 and R4 are paired photoreceptors which contribute the outer rhabdomeres.

The process during which the R7 photoreceptor commits to its cell fate. The R7 receptor contributes the central part of the rhabdomere in the apical parts of the ommatidium.

cone cell fate commitment (sensu Endopterygota)

The process during which the cone cells of the eye, the lens-secreting cells in the ommatidia, adopt pathways of differentiation that lead to the establishment of their distinct cell type. As in, but not restricted to, the Holometabola (Endopterygota, ncbi_taxonomy_id:33392).

photoreceptor cell differentiation (sensu Endopterygota)

The process whereby a relatively unspecialized cell acquires the specialized features of a photoreceptor cell, the receptor that responds to light. As in, but not restricted to, the Holometabola (Endopterygota, ncbi_taxonomy_id:33392).

protein phosphatase type 2B, intrinsic catalyst activity

Catalysis of the reaction: a phosphoprotein + n H2O = a protein + n phosphate.

Any process that modulates the frequency, rate or extent of rhodopsin gene activity. This includes transcriptional, translational, or posttranslational regulation.

Formation and development of the sensory structures on the head that are capable of detecting various environmental stimuli.

dorsal/ventral pattern formation, imaginal disc

The establishment, maintenance and elaboration of the dorsal/ventral axis of the imaginal disc. Imaginal disks are masses of hypodermic cells, carried by the larvae of some insects after leaving the egg, from which masses the wings and legs of the adult are subsequently formed.

Interacting selectively with the interleukin-17E receptor.

dorsal/ventral lineage restriction, imaginal disc

Formation and/or maintenance of a lineage boundary between dorsal and ventral compartments that cells cannot cross, thus separating the populations of cells in each compartment.

eggshell pattern formation (sensu Insecta)
