Immunogen A synthetic peptide from the 1t cytoplasmic loop of human TRPC3 conjugated to an immunogenic carrier protein was used as the antigen. The antigen shares 85% identity with TRPC6 and TRPC7.
Specificity Appears to recognise TRPC3, TRPC6 and TRPC7.
Purification Whole serum
Alternative Name TRPC3, 6, 7
Background Function: Thought to form a receptor-activated non-selective calcium permeant cation channel. Probably is operated by a phosphatidylinositol second messenger system activated by receptor tyrosine kinases or G-protein coupled receptors. Activated by diacylglycerol (DAG) in a membrane-delimited fashion, independently of protein kinase C, and by inositol-1,4,5-triphosphate receptors (ITPR) with bound IP3. May also be activated by internal calcium store depletion.
Subcellular location: Membrane, Multi-pass membrane protein.
Tissue specificity: Abundantly expressed in brain. Concentrated in cerebellar Purkinje cells and sparsely localized in cerebellar granule lyer, pontine nuclei and thalamus. Lower levels detected in other tissues. Also known as: Short transient receptor potential channel 3, TrpC3, Htrp-3, trp3, transient receptor potential cation channel, subfamily C, member 3.
Application Notes 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.
