Calphotin (Cpn) encodes a glutamic acid-rich protein with a strong negative charge and a highly hydrophobic amino acid composition. It functions as an immobile Ca[2+] buffer along the base of the photoreceptor's microvilli. It protects the photoreceptor cells from Ca[2+] overload and light induced degeneration.

Eclosion hormone (Eh) encodes a neurohormone involved in the control of ecdysis. At each ecdysis, the neurohormone is released into the hemolymph where it serves to potentiate the release of the product of ETH through a positive endocrine feedback loop. The product of Eh is also released into the nervous system where it contributes to turning on ecdysis.

Rhodopsin 3 (Rh3) encodes a Rhodopsin GPCR protein that responds to UV light and activates the phototransduction cascade that leads to photoreceptor depolarization. Rh3 is expressed in R7 photoreceptors in a stochastic manner: 35% of R7 photoreceptors express Rh3 while the remaining 65% express another UV-sensitive Rhodopsin encoded by Rh4.

Pico, isoform A; Pico (pico) encodes an intracellular adapter protein belonging to the MRL family of proteins, which transduce signals from growth factor receptors to changes in the actin cytoskeleton. Its roles include the regulation of growth and cell migration.

Protein phyllopod; Essential adapter component of E3 ubiquitin ligase complexes; involved in R7 photoreceptor cell differentiation, embryonic nervous system, external sensory organ development and specification of particular muscles. E3 ubiquitin ligase complexes mediate ubiquitination and subsequent proteasomal degradation of target proteins. Required for specification of R7 photoreceptor cell fate in the eye by participating in the ubiquitination and subsequent proteasomal degradation of Tramtrack (ttk), a general inhibitor of photoreceptor differentiation. Acts downstream of Notch s [...]

Larval translucida (ltl) encodes a leucine-rich repeat protein involved in wing vein specification.

Leucine-rich repeat kinase (Lrrk) encodes a large Ser/Thr kinase involved in mRNA translational control, cytoskeleton regulation, vesicle trafficking, autophagy, and immune response.

Dynein light chain Tctex-type; Acts as one of several non-catalytic accessory components of the cytoplasmic dynein complex that are thought to be involved in linking dynein to cargos and to adapter proteins that regulate dynein function. Cytoplasmic dynein acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. Required for spermatid differentiation. Is not required for polarized transport in rhabdomere development and appears to be a non-essential component of the cytoplasmic dynein complex.

SP555, isoform A; It is involved in the biological process described with: proteasome-mediated ubiquitin-dependent protein catabolic process; ubiquitin-dependent protein catabolic process.
