Background Information
SFRS2, also named as PR264 and Splicing component, 35 kDa, belongs to the splicing factor SR family. SFRS2 is necessary for the splicing of pre-mRNA. Some residue of SFRS2 is modified by phosphorylase and acetylase after translation. The molecular weight of modified SFRS2 is 35-40kDa. It is required for formation of the earliest ATP-dependent splicing complex and interacts with spliceosomal components bound to both the 5'- and 3'-splice sites during spliceosome assembly. It also is required for ATP-dependent interactions of both U1 and U2 snRNPs with pre-mRNA. It binds to purine-rich RNA sequences, either 5'-AGSAGAGTA-3' (S=C or G) or 5'-GTTCGAGTA-3'. SFRS2 can bind to beta-globin mRNA and commit it to the splicing pathway. The antibody has no cross reaction to SFRS2B.

FH Xingyuan (Verified Customer) (07-17-2023) | The quality of SRSF2's antibody wasn't good. I was not able to see bands at around 37kDa (tried 3 times).
