Abstract
Selenoprotein M (SelM) was discovered using computational analysis of signature sequences found in all eukaryotic selenoprotein genes. Located within the endoplasmic reticulum, SelM contains a cysteine-X-X-selenocysteine redox motif, and is most abundantly expressed in the brain. We carried out stable overexpression of SelM in two cell lines of neuronal origin, murine HT22 hippocampal cells and murine C8-D1A cerebellar astrocytes. In addition, stable knockdown was carried out in HT22 cells and transient knockdown in primary murine neuronal cultures. Our studies manipulating the expression of SelM indicate it is a neuroprotective antioxidant, and is involved in calcium regulation.
