A Researcher’s Guide to Calretinin as a Neuroscience and Histology Marker
Calcium-binding proteins play an outsized role in how neurons manage signaling, and few are studied as widely as calretinin. For scientists working in neuroscience, developmental biology, or diagnostic pathology, having a dependable antibody against this protein is often central to getting clean, reproducible results on a Western blot or a tissue section.
What Calretinin Does in the Body
Calretinin, encoded by the CALB2 gene, belongs to the calbindin family of calcium-binding proteins and contains six EF-hand domains that allow it to buffer intracellular calcium. It is abundantly expressed throughout the central nervous system, the retina, and several peripheral tissues. Research has suggested that calretinin contributes to neuroprotection by helping neurons manage calcium overload, whic...
