SART1 Plays a role in mRNA splicing as a component of the U4/U6-U5 tri-snRNP, one of the building blocks of the spliceosome. May also bind to DNA. Belongs to the SNU66/SART1 family. Ubiquitously expressed. 1 alternatively spliced human isoform has been reported. Note: This description may include information from UniProtKB.
