Biological background
Protein function (datasheet): Buffers cytosolic calcium. May stimulate a membrane Ca (2+)-ATPase and a 3',5'-cyclic nucleotide phosphodiesterase.
Scientific background (datasheet): Calbindin is a calcium-binding protein belonging to the troponin C superfamily. Calretinin is expressed in central and peripheral nervous system and in many normal and pathological tissues. The rat and human calretinin exhibit 98% sequence homology and 91% homology to many other species. Two calcium binding proteins, calbindin and calretinin, have been reported to be expressed in abundance in Purkinje cells and other cell types in the cerebellum.
Cellular localization (datasheet): Cytoplasm. Nucleus. Cell membrane; Peripheral membrane protein. Localizes within both nucleus and cytoplasm of proliferative primary myoblasts and mostly within the nucleus of differentiated primary myoblasts. By virtue of the N-terminal PH domain, is recruited to sites of the plasma membrane containing increased PI (3,4,5)P3 or PI (3,4)P2, cell membrane targeting is also facilitared by interaction with CLIP3.
Tissue details (datasheet): Expressed in all cell types so far analyzed.
Sequence similarities (datasheet): Belongs to the calbindin family.
Research relevance and current trends
- Commonly studied in contexts related to Calcium Binding Proteins,Calcium Signaling,Cell Type Marker,Neuron Marker,Neuroscience,Neurotransmission.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- ELISA: Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.
- Immunohistochemistry (IHC): Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.
- Flow cytometry: Quantify target-positive populations in single-cell suspensions; pair with viability and isotype/FMO controls conceptually.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.
