Sars

Functionⁱ

Catalyzes the attachment of serine to tRNA(Ser) in a two-step reaction: serine is first activated by ATP to form Ser-AMP and then transferred to the acceptor end of tRNA(Ser). Is probably also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L-seryl-tRNA(Sec), which will be further converted into selenocysteinyl-tRNA(Sec). In the nucleus, binds to the VEGFA core promoter and prevents MYC binding and transcriptional activation by MYC. Recruits SIRT2 to the VEGFA promoter, promoting deacetylation of histone H4 at 'Lys-16' (H4K16). Thereby, inhibits the production of VEGFA and sprouting angiogenesis mediated by VEGFA.By similarity

Catalytic activityⁱ

ATP + L-serine + tRNA(Ser) = AMP + diphosphate + L-seryl-tRNA(Ser).By similarity

ATP + L-serine + tRNA(Sec) = AMP + diphosphate + L-seryl-tRNA(Sec).By similarity

Pathwayⁱ: selenocysteinyl-tRNA(Sec) biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-seryl-tRNA(Sec) from L-serine and tRNA(Sec).
Proteins known to be involved in this subpathway in this organism are:

Serine--tRNA ligase, cytoplasmic (Sars)

This subpathway is part of the pathway selenocysteinyl-tRNA(Sec) biosynthesis, which is itself part of Aminoacyl-tRNA biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-seryl-tRNA(Sec) from L-serine and tRNA(Sec), the pathway selenocysteinyl-tRNA(Sec) biosynthesis and in Aminoacyl-tRNA biosynthesis.
