100 µg peptide, lyophilized. For reconstitution add 100 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Control peptides should be stored at -20°C when still lyophilized! |
| Applications |
|
| Immunogen | Synthetic peptide corresponding to AA 939 to 948 from rat Erc1b (UniProt Id: Q811U3-1) |
| Recommended dilution | Optimal concentrations should be determined by the end-user. |
| Matching antibodies | 143 003, 143 004 |
| Remarks |
This control peptide consists of the synthetic peptide CDQDEEEGIWA (aa 939 - 948 in rat ERC 1b) that has been used for immunization. It has been tested in preadsorption experiments and blocks efficiently and specifically the corresponding signal in Western blots. The amount of protein needed for efficient blocking depends on the titer and on the affinity of the antibody to the antigen. |

ELKS, also referred to as ERCs (ERC 1 and ERC 2) and CAST, are related proteins which share an identical C-terminal sequence. They interact with the conserved RIM PDZ domain via an unusual PDZ binding motif. Two splice variants of ERC 1 (1a and 1b) have been described. ERC 1b (CAST 2a) binds to RIM and is expressed exclusively in the brain. ERC 1a is a ubiquitously expressed cytosolic protein. ERC 2 (CAST 1) is only expressed as a single RIM binding variant.
All ERCs have been shown to interact with Rab 6, a protein involved in membrane trafficking at the Golgi complex. The function of these proteins has not been determined yet. They may link Rab 6 mediated non-neuronal membrane traffic at the Golgi complex to neuronal membrane traffic at the active zone executed via RIMs.
