Calretinin also known as 29 kDa calbindin is a vitamin D-dependent calcium-binding protein involved in calcium signaling. In humans, the calretinin protein is encoded by the CALB2 gene.[1][2]
Function
This gene encodes an intracellular calcium-binding protein belonging to the troponin C superfamily. Members of this protein family have six EF-hand domains which bind calcium. This protein plays a role in diverse cellular functions, including message targeting and intracellular calcium buffering. It also functions as a modulator of neuronal excitability, and is a diagnostic marker for some human diseases, including Hirschsprung disease and some cancers.[1]
Calretinin is abundantly expressed in neurons and in hair follicles.[3]
Clinical significance
Using immunohistochemistry, calretinin can be demonstrated in both benign mesothelium and in malignant mesothelioma[4] and can be used to help differentiate different lung tumours.[5] Antibodies to calretinin can also be used to distinguish between different types of brain tumour, demonstrating only those with neuronal rather than glial, differentiation.[6]
