Additional Information

Alternative name: TRPM7 (LTRPC7)

UniProt: Q96QT4

Immunogen: A synthetic peptide from the 4th cytoplasmic loop of human TRPM7 (LTRPC7) conjugated to an immunogenic carrier protein was used as the immunogen. The antigen is homologous in rat, mouse, monkey and sheep.

Format: Lyophilized

Description: TRPCs, mammalian homologs of the Drosophila transient receptor potential (trp) protein, are ion channels that are thought to mediate capacitative calcium entry into the cell. TRP-PLIK is a protein that is both an ion channel and a kinase. As a channel, it conducts calcium and monovalent cations to depolarize cells and increase intracellular calcium. As a kinase, it is capable of phosphorylating itself and other substrates. The kinase activity is necessary for channel function, as shown by its dependence on intracellular ATP and by the kinase mutants. FUNCTION: Essential ion channel and serine/threonine-protein kinase. Divalent cation channel permeable to calcium and magnesium. Has a central role in magnesium ion homeostasis and in the regulation of anoxic neuronal cell death. The kinase activity is essential for the channel function. May be involved in a fundamental process that adjusts plasma membrane divalent cation fluxes according to the metabolic state of the cell. Phosphorylates annexin A1 (ANXA1). CATALYTIC ACTIVITY: ATP + a protein: ADP + a phosphoprotein. COFACTOR: Binds 1 zinc ion per subunit. SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein. Also known as: Transient receptor potential cation channel subfamily M member 7, long transient receptor potential channel 7, LTrpC7, channel-kinase 1, CHAK1, LTRPC7, CHAK, FLJ20117, FLJ25718, TRP-PLIK.

Specificity: Appears to be specific for TRPM7.

Application Details

Application Notes: IHC, WB. A dilution of 1 : 300 to 1 : 2000 is recommended. The optimal dilution should be determined by the end user. Not yet tested in other applications.

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
