Calbindin 1 is a protein that in humans is encoded by the CALB1 gene. It belongs to the calbindin family of calcium-binding proteins, along with calretinin (CALB2). [5]

Function

edit

The protein encoded by this gene is a member of the calcium-binding protein superfamily that includes calmodulin and troponin C. Originally described as a 27 kDa protein, it is now known to be a 28 kDa protein. It contains four active calcium-binding domains, and has two modified domains that are thought to have lost their calcium binding capability.[6] This protein is thought to buffer entry of calcium upon stimulation of glutamate receptors. Depletion of this protein was noted in patients with Huntington disease. [provided by RefSeq, Jan 2015].
