Summary: Rtf2 RING-finger
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.
Rtf2 RING-finger Provide feedback
It is vital for effective cell-replication that replication is not stalled at any point by, for instance, damaged bases. Replication termination factor 2 (Rtf2) stabilizes the replication fork stalled at the site-specific replication barrier RTS1 by preventing replication restart until completion of DNA synthesis by a converging replication fork initiated at a flanking origin. The RTS1 element terminates replication forks that are moving in the cen2-distal direction while allowing forks moving in the cen2-proximal direction to pass through the region. Rtf2 contains a C2HC2 motif related to the C3HC4 RING-finger motif, and would appear to fold up, creating a RING finger-like structure but forming only one functional Zn2+ ion-binding site . This domain is also found at the N-terminus of peptidyl-prolyl cis-trans isomerase 4, a divergent cyclophilin family .

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request
