Additional Information

Alternative name: TRP (Transient receptor potential protein) (4th cytoplasmic loop)

Immunogen: A synthetic peptide from 4th cytoplasmic loop of drosophila TRP (Transient receptor potential protein) conjugated to an immunogenic carrier protein was used as the immunogen.

Format: Lyophilized

Description: FUNCTION: A light-sensitive calcium channel that is required for inositide-mediated Ca(2+) entry in the retina during phospholipase C (PLC)-mediated phototransduction. Ca(2+) influx may then feed back and inhibit PLC, thereby facilitating phosphatidylinositol 4,5 bisphosphate (PIP2) recycling. Trp and trpl act together in the light response, though it is unclear whether as heteromultimers or as distinct units, and are activated by fatty acids and metabolic stress. Also required forolfactory adaptation and may be involved inolfactory system development. SUBUNIT: The C-terminus interacts with a PDZ domain of inaD to form the core of the inaD signaling complex. Other members of the complex include norpA (PLC), inaC (PKC), and possibly trpl, ninaC, FKBP59, calmodulin and rhodopsin. Forms homomultimers and heteromultimers with trpl. Interaction with trpl is mediated in part by the N-terminal region and thetransmembrane domains. Also interacts, though to a lower extent, with trp-gamma. SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein. Note: Localized on plasma membrane loops found at the base of the rhabdomere, in close proximity to the calcium stores. TISSUE SPECIFICITY: Expressed predominantly in the rhabdomeres of photoreceptor cells. Expressed in the third antennal segment and in theolfactory segment at approximately 70 hours after puparium formation during antennal development. Also known as: Transient receptor potential cation channel protein.

Specificity: Appears to be specific for TRP.

Application Details

Application Notes: IHC, WB. A dilution of 1 : 300 to 1 : 4000 is recommended. The optimal dilution should be determined by the end user.

Purity: whole serum

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Restrictions: For Research Use only
