Summary: Prokaryotic RING finger family 2
Prokaryotic RING finger family 2 Provide feedback
RING finger family found sporadically in bacteria and archaea, and associated with other components of the ubiquitin-based signaling and degradation system, including ubiquitin and the E1 and E2 proteins. The bacterial versions contain transmembrane helices .

This entry represents a RING finger family found sporadically in bacteria and archaea, and associated with other components of the ubiquitin-based signaling and degradation system, including ubiquitin and the E1 and E2 proteins. The bacterial versions contain transmembrane helices [PUBMED:21547297].

This clan includes the Ring zinc finger domains as well as the U-box domain that appears to have lost the zinc coordinating cysteine residues .
The clan contains the following 24 members:Baculo_RING FANCL_C Prok-RING_1 Prok-RING_2 Prok-RING_4 RINGv Rtf2 U-box zf-Apc11 zf-C3HC4 zf-C3HC4_2 zf-C3HC4_3 zf-C3HC4_4 zf-MIZ zf-Nse zf-rbx1 zf-RING-like zf-RING_2 zf-RING_4 zf-RING_5 zf-RING_6 zf-RING_UBOX zf-UBP zf-UDP
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
