Publication Abstract from PubMed

Prp28 (pre-mRNA-splicing ATP-dependent RNA helicase 28) is a spliceosomal DEAD-box helicase which is involved in two steps of spliceosome assembly. It is required for the formation of commitment complex 2 in an ATP-independent manner as well as for the formation of the pre-catalytic spliceosome, which in contrast is ATP-dependent. During the latter step, Prp28 is crucial for the integration of the U4/U6.U5 tri-snRNP since it displaces the U1 snRNP and allows the U6 snRNP to base-pair with the 5'-splice site. Here, the crystal structure of Prp28 from the thermophilic fungus Chaetomium thermophilum is reported at 3.2 A resolution and is compared with the available structures of homologues.
