Biol. 390:747-759(2009). CC -!- FUNCTION: Synthesizes selenophosphate from selenide and ATP. CC -!- CATALYTIC ACTIVITY: ATP + selenide + H(2)O = AMP + selenophosphate CC + phosphate. CC -!- ENZYME REGULATION: Activated by phosphate ions and by potassium CC ions. CC -!- SUBUNIT: Homodimer (isoform 1, isoform 2, isoform 3 and isoform CC 4). Heterodimer of isoform 1 and isoform 3. Heterodimer of isoform CC 2 and isoform 4. CC -!- SUBCELLULAR LOCATION: Isoform 1: Cell membrane. Nucleus membrane. CC -!- SUBCELLULAR LOCATION: Isoform 2: Cytoplasm.

Isoform 3 is gradually expressed during the cell cycle CC until S phase and then decreased. CC -!- SIMILARITY: Belongs to the selenophosphate synthase 1 family. CC Class II subfamily. CC -!- CAUTION: The conserved active site Cys (or selenocysteine) residue CC in position 29 is replaced by a Thr. However, as function in CC selenoprotein synthesis is proven, it is possible Cys-31 is the CC active site.
