Anti-CABP4 antibodies are used in the immunodetection of the protein calcium binding protein 4. In humans, the canonical protein has a reported length of 275 amino acid residues and a mass of 30.4 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in retina and in the inner hair cells (IHC) of the cochlea. CABP4 is known to be involved in normal synaptic function through regulation of Ca(2+) influx and neurotransmitter release in photoreceptor synaptic terminals and in auditory transmission. Post-translational modifications have been described, including phosphorylation. The CABP4 gene has been associated with the disease, Cone-rod synaptic disorder. CABP4 gene orthologs have been reported in the mouse, bovine and chimpanzee species. Western Blot is a widely used application for the CABP4 antibodies listed below. In addition, ELISA is also a common application.
