    The Calcium homoeostasis endoplasmic reticulum protein (CHERP) gene has been recently identified and localized on chromosome 19p13.1. CHERP has high homology to an SR related CTD protein, which is known to interact with the largest subunit of RNA polymerase II. CHERP is an integral endoplasmic reticulum membrane protein is involved in calcium mobilization induced by thrombin. Confocal microscopy revealed that CHERP is associated with Ins(1,4,5)P3 receptor throughout the cytoplasm and perinuclear region in Jurkat T lymphocyte. CHERP Anti sense treatment induced a decrease in CHERP, which caused an impaired increase in free cytoplasmic calcium but calcium influx remains unaffected, with some deficient in endoplasmic reticulum calcium stores. In the CHERP depleted Jurkat T lymphocytes the calcium dependent translocation of nuclear factor of activated T cells (NFAT) from cytoplasm to nucleus was also suppressed with significant suppression of cell.
  • Cellular localization
    Cytoplasm. Cytoplasm; perinuclear region. Endoplasmic reticulum. Note: Distributed throughout the cytoplasm and also localizes to the perinuclear region of both human erythroleukemia (HEL) cells and Jurkat cells. Colocalizes with ITPR1.

  • Immunofluorescence analysis of HEK293 cells, staining CHERP with ab15951.
    Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 1% BSA. Cells were incubated with primary antibody at 4°C overnight. A fluorescent-conjugated anti-rabbit IgG was used as a secondary antibody.

Thank you for contacting us. The immunogen, a peptide (17mer), was synthesized, and the sequence is taken from within the C-terminal region spanning between aa 875-916. The peptide was 100% conserved in human, rat and mouse protein. The peptide was modified by adding a Cysteine on C-terminal end and conjugated to KLH for antigen preparation.

I hope this helps. Please let me know if you have other questions.

Thank you for your enquiry. We will not be able to provide the exact immunogen sequence unless I can convince the originating laboratory to release it. (They consider it proprietary information). We do know that the immunogen is from the the N-terminal end, a 21 aa peptide sequence between amino acids 25-65 of the RICH2 protein (human).

If there is a particular species you want to align with the immunogen, could you please send the sequence or the accession number? I will forward it to the laboratory for alignment.

Thank you for contacting us. The exact sequence of the immunogen is considred proprietary but there is 100% homology with all three of the species, mouse, rat and human.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for contacting Abcam. The antibody epitope was form the N-terminal end, the 21 aa peptide sequence lies between amino acids********of the RICH2 protein (human).  Therefore I am unsure as to why this antibody cannot detect your C-terminal deletion mutants but can detect the endogenous protein. Are you able to measure the levels of your truncation mutants, does it have a tag on it. I am wondering if there are just low levels of the truncated protein in general. If there is anything else I can help you with, please let me know.
