Protein
U1 snRNP-associated protein usp106
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843)
Function
Component of the U1 snRNP particle, which recognizes and binds the 5'-splice site of pre-mRNA. Together with other non-snRNP factors, U1 snRNP forms the spliceosomal commitment complex, that targets pre-mRNA to the splicing pathway.
Similarity
Belongs to the Luc7 family.
