The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 5 µg/ml.
Use a concentration of 1 µg/ml. Detects a band of approximately 112 kDa (predicted molecular weight: 112 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Form a receptor-activated non-selective calcium permeant cation channel. Acts as a cell-cell contact-dependent endothelial calcium entry channel. Probably operated by a phosphatidylinositol second messenger system activated by receptor tyrosine kinases or G-protein coupled receptors. Mediates cation entry, with an enhanced permeability to barium over calcium. May also be activated by intracellular calcium store depletion.
Strongly expressed in placenta. Expressed at lower levels in heart, pancreas, kidney and brain. Expressed in endothelial cells. Isoform alpha was found to be the predominant isoform. Isoform beta was not found in pancreas and brain.
Belongs to the transient receptor (TC 1.A.4) family. STrpC subfamily. TRPC4 sub-subfamily. Contains 4 ANK repeats.
The protein 4.1-binding domain (654-685) is required for binding to EPB41L2 and channel activation. The calmodulin- and inositol 1,4,5-trisphosphate receptor-binding (CIRB) domain (695-724) is sufficient for the interaction with SESTD1. The spectrin-binding domain (730-758) is required for binding to SPTAN1 and SPTBN5.
Phosphorylation modulates TRPC channel function by regulating the level of TRPC4 at the cell surface and by increasing the association with SLC9A3R1/NHERF.
Membrane. Cell membrane. Enhanced insertion into the cell membrane after activation of the EGF receptor.
