Summary: Peptidase C65 Otubain
Peptidase C65 Otubain Provide feedback
This family of proteins conserved from plants to humans is a highly specific ubiquitin iso-peptidase that removes ubiquitin from proteins. The modification of cellular proteins by ubiquitin (Ub) is an important event that underlies protein stability and function in eukaryote being a dynamic and reversible process. Otubain carries several key conserved domains: (i) the OTU (ovarian tumour domain) in which there is an active cysteine protease triad (ii) a nuclear localisation signal, (iii) a Ub interaction motif (UIM)-like motif phi-xx-A-xxxs-xx-Ac (where phi indicates an aromatic amino acid, x indicates any amino acid and Ac indicates an acidic amino acid), (iv) a Ub-associated (UBA)-like domain and (v) the LxxLL motif.

This family of proteins is a highly specific ubiquitin iso-peptidase that removes ubiquitin from proteins [PUBMED:12704427]. The modification of cellular proteins by ubiquitin (Ub) is an important event that underlies protein stability and function in eukaryotes, as it is a dynamic and reversible process. Otubain carries several key conserved domains: (i) the OTU (ovarian tumour domain) in which there is an active cysteine protease triad (ii) a nuclear localisation signal, (iii) a Ub interaction motif (UIM)-like motif phi-xx-A-xxxs-xx-Ac (where phi indicates an aromatic amino acid, x indicates any amino acid and Ac indicates an acidic amino acid), (iv) a Ub-associated (UBA)-like domain and (v) the LxxLL motif.

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 UniProtKB sequence database using the family HMM
- 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:

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the Peptidase_C65 domain has been found. There are 29 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
