SEPSECS encodes selenocysteine synthase, a core enzyme in selenoprotein biosynthesis. This protein catalyzes the conversion of serine-charged tRNA(Sec) to selenocysteine-charged tRNA(Sec) by replacing serine’s hydroxyl group with selenide, using pyridoxal 5'-phosphate as a cofactor. Common aliases include SEPSEC and selenocysteine synthase 1.
Dysfunction of SEPSECS disrupts selenoprotein production, linking to neurodegenerative conditions like progressive cerebello-cerebral atrophy and spinal muscular atrophy with cerebellar atrophy. Current research explores selenium supplementation as supportive therapy, while preclinical studies investigate targeted modulators of the selenoprotein biosynthetic pathway for related disorders.

IHC image of CSB-PA14389A0Rb diluted at 1:100 and staining in paraffin-embedded human liver tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB. Secondary antibody only control: uses 1% BSA instead of primary antibody
