Trp-Like (TRPL) (4th Cytoplasmic Loop) antibody

Antigen: Trp-Like (TRPL)

Binding Site: 4th Cytoplasmic Loop

Clonality: Polyclonal

Host: Rabbit

Reactivity: Fruit Fly (Drosophila melanogaster)

Application: Immunohistochemistry (IHC), Western Blotting (WB)

Catalog no.: ABIN351176

Additional Information

Alternative name: TRPL (Transient receptor potential like protein)

UniProt: P48994

Immunogen: A synthetic peptide from 4th cytoplasmic loop of drosophila TRPL (Transient receptor potential like 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. 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 trp-gamma. Activated by fatty acids, metabolic stress, inositols and GTP-binding proteins. SUBUNIT: Forms heteromultimers with trp-gamma and, to a lower extent, with trp. Interacts with FKBP59 in vivo and is found in the inaD signaling complex. SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein. Note: In the dark, there is 20 fold more rhabdomeral trpl protein forming plasma membrane channels than in the light. In the light, the protein translocates to an intracellular compartment. Protein levels remain unchanged in light and dark conditions. Also known as: Transient receptor potential like protein, Transient-receptor-potential-like protein.

Specificity: Appears to be specific for TRPL.

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
