Protein
Pre-mRNA-splicing factor CLF1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Involved in pre-mRNA splicing and cell cycle progression. Required for the spliceosome assembly by promoting the functional integration of the U4/U6.U5 tri-snRNP particle into the U1-, U2-dependent pre-spliceosome. Also recruits PRP19 to the spliceosome, as a component of the NTC complex (or PRP19-associated complex). The association of the NTC complex to the spliceosome mediates conformational rearrangement or stabilizes the structure of the spliceosome after U4 snRNA dissociation, which leads to spliceosome maturation. Required for initiation of the DNA replication by binding the RNA replication origins, probably through its interaction with the origin recognition complex (ORC).
Similarity
Belongs to the crooked-neck family.
