Calmodulin (CaM) is a ubiquitous intracellular calcium receptor that regulates a plethora of cellular functions through interactions with target proteins. In mammals, an identical Calmodulin protein is expressed by 3 independent genes (CALM1, CALM2, CALM3). Therefore, antibodies generated against either of the three products (CaM1, CaM2, CaM3) of these genes cannot be distinguished, and conclusions based on the supposedly specific CaM antibodies claiming functions of one of the 3 genes may be misleading. In this paper we present 44 articles, using such antibodies for Western blot, ELISA assay, immunohistochemistry or which are based on proteomics and the use of databases with incorrect annotations, all potentially reaching misleading conclusions. This should be taken as a note of caution for researchers working with Calmodulin antibodies and misleading databases.
期刊介绍：
The Journal of Immunological Methods is devoted to covering techniques for: (1) Quantitating and detecting antibodies and/or antigens. (2) Purifying immunoglobulins, lymphokines and other molecules of the immune system. (3) Isolating antigens and other substances important in immunological processes. (4) Labelling antigens and antibodies. (5) Localizing antigens and/or antibodies in tissues and cells. (6) Detecting, and fractionating immunocompetent cells. (7) Assaying for cellular immunity. (8) Documenting cell-cell interactions. (9) Initiating immunity and unresponsiveness. (10) Transplanting tissues. (11) Studying items closely related to immunity such as complement, reticuloendothelial system and others. (12) Molecular techniques for studying immune cells and their receptors. (13) Imaging of the immune system. (14) Methods for production or their fragments in eukaryotic and prokaryotic cells.
In addition the journal will publish articles on novel methods for analysing the organization, structure and expression of genes for immunologically important molecules such as immunoglobulins, T cell receptors and accessory molecules involved in antigen recognition, processing and presentation. Submitted full length manuscripts should describe new methods of broad applicability to immunology and not simply the application of an established method to a particular substance - although papers describing such applications may be considered for publication as a short Technical Note. Review articles will also be published by the Journal of Immunological Methods. In general these manuscripts are by solicitation however anyone interested in submitting a review can contact the Reviews Editor and provide an outline of the proposed review.
