Domain

Suppressor of forked (IPR008847)

Short name: Suf

Domain relationships

None.

Description

This domain consists of several eukaryotic suppressor of forked (Suf) like proteins. The Drosophila melanogaster suppressor of forked [Su(f)] protein shares homology with the Saccharomyces cerevisiae RNA14 protein and the 77 kDa subunit of Homo sapiens cleavage stimulation factor, which are proteins involved in mRNA 3' end formation. This suggests a role for Su(f) in mRNA 3' end formation in Drosophila. The su(f) gene produces three transcripts; two of them are polyadenylated at the end of the transcription unit, and one is a truncated transcript, polyadenylated in intron 4. It is thought that su(f) plays a role in the regulation of poly(A) site utilisation and the GU-rich sequence is important for this regulation to occur [PMID: 9826695].
