Active Recombinant Human SRSF1, His-tagged

• Cat.No.: SRSF1-8494H
• Product Overview: Recombinant Human SRSF1, fused with His tag, was expressed in Sf21 Cells.

Specification

• Description: ASF also known as SF2 is a member of the SR protein family. It is an essential pre-mRNA splicing factor required for both single and alternative splicing. Phosphorylation on serine residues located within the SR domain directly regulates ASF/SF2 activity and compartmentalization of other SR splicing factors. In addition to interacting with RNA and other splicing factors, such as U1-70K, U2AF and other SR proteins, ASF/SF2 also directly or indirectly interacts with HIV regulatory protein Rev, the C-terminal domain (CTD) of the largest subunit of RNA polymerase II, and numerous transcription factors, thereby suggesting a potential role of ASF/SF2 in coordinating transcription and pre-mRNA splicing .
