Protein Domain
Type: Domain
Description: This entry represents the RNA recognition motif(RRM) of SCAF4 (also known as Splicing factor, arginine/serine-rich 15) that belongs to a new class of SCAFs (SR-like CTD-associated factors). Although its biological function remains unclear, SCAF4 shows high sequence similarity to SCAF8 that interacts specifically with a highly serine-phosphorylated form of the carboxy-terminal domain (CTD) of the largest subunit of RNA polymerase II (pol II) and may play a direct role in coupling with both, transcription and pre-mRNA processing, processes []. SCAF4 and SCAF8 both contain a conserved N-terminal CTD-interacting domain (CID), an atypical RNA recognition motif (RRM) and serine/arginine-rich motifs.
Protein Domain
Type: Domain
Description: The C-terminal domain (CTD) of the large subunit of RNA polymerase II is aplatform for mRNA processing factors and links gene transcription to mRNAcapping, splicing and polyadenylation. CTD recognition is dependent on thephosphorylation state of the CTD itself, which varies during the course oftranscription but has also been linked to the isomerization state of the CTD'sproline residues. Several RNA-processing factors recognise the CTD by means ofa conserved CTD-interacting domain (CID). Factors with CID domains include theserine/arginine-rich-like factors SCAF4 and SCAF8, Nrd1 (which is implicatedin polyadenylation-independent RNA 3'-end formation) and Pcf11. Pcf11 is aconserved and essential subunit of the yeast cleavage factor 1A, which isrequired for 3'-RNA processing and transcription termination [, ].The CID domain is a right-handed superhelix of eight α-helices forming acompact domain. The CID fold closely resembles that of VHSdomains and is related to armadillo-repeat proteins , except for the two amino-terminal helices. Amino acid residuesin the hydrophobic core of the domain are highly conserved across CID domains[, ].
