Myosin heavy chain 95F; Myosin is a protein that binds to actin and has ATPase activity that is activated by actin. Together CLIP-190 and jar may coordinate the interaction between the actin and microtubule cytoskeleton. May link endocytic vesicles to microtubules and may be involved in transport in the early embryo and in the dynamic process of dorsal closure. It is believed that its function changes during the life cycle.

Inactivation-no-after-potential D protein; Involved in the negative feedback regulation of the light- activated signaling cascade in photoreceptors through a calcium- mediated process. Interacts with tetrapeptide ligand located in C- terminal sequence of 3 key components of the visual cascade, tethering them and forming a macromolecular signaling phototransduction complex.

Dynamin; Microtubule-associated force-producing protein which is involved in the production of microtubule bundles and which is able to bind and hydrolyze GTP. Implicated in endocytic protein sorting; Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family.

Tropomyosin-1, isoforms 9A/A/B; Tropomyosin, in association with the troponin complex, plays a central role in the calcium dependent regulation of muscle contraction; Belongs to the tropomyosin family.

Calmodulin; Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+) (By similarity). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases (By similarity). In photoreceptor cells, light-induced Ca(2+) influx activates calmodulin, which in turn is likely to promote Crag activity in trafficking of newly synthesized ninaE (Rh1) from the trans-Golgi network to rhabdomere membranes. Together with Akap200, regulates PKA activity and ethanol-induced sensitivity and tolerance.

Cortactin, isoform A; Proline-rich region binding; actin filament binding.

Inositol 1,4,5,-trisphosphate receptor (Itpr) encodes an intracellular ligand gated calcium channel. It functions downstream of G-protein coupled receptors that activate Gq/PLCbeta signaling and generate inositol tris-phosphate. Itpr depletion affects ecdysone release, response to nutritional stress, lipid metabolism and flight; Belongs to the InsP3 receptor family.

AT09290p.

Transient-receptor-potential-like protein; A light-sensitive calcium channel that is required for inositide-mediated Ca(2+) entry in the retina during phospholipase C (PLC)-mediated phototransduction. Required for vision in the dark and in dim light. Binds calmodulin. Trp and trpl act together in the light response, although it is unclear whether as heteromultimers or distinct units. Also forms a functional cation channel with Trpgamma. Activated by fatty acids, metabolic stress, inositols and GTP-binding proteins.
