Summary: Stannin unstructured linker
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.
Stannin unstructured linker Provide feedback
Members of this family are unstructured, acting as connectors of the stannin helical domains. They contain a conserved CXC metal-binding motif and a putative 14-3-3-zeta binding domain. Upon coordinating dimethytin, considerable structural or dynamic changes in the flexible loop region of SNN may take place, recruiting other binding partners such as 14-3-3-zeta, and thereby initiating the apoptotic cascade .

InterPro entry IPR015136
This entry represents an unstructured protein region which connects two adjacent stannin helical domains. It contains a conserved CXC metal-binding motif and a putative 14-3-3-zeta binding domain. Upon coordinating dimethytin, considerable structural or dynamic changes in the flexible loop region of SNN may take place, recruiting other binding partners such as 14-3-3-zeta, and thereby initiating the apoptotic cascade [PUBMED:16246365].

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

You can use the tree controls to manipulate how the interactive tree is displayed:
- show/hide the summary boxes
- highlight species that are represented in the seed alignment
- expand/collapse the tree or expand it to a given depth
- select a sub-tree or a set of species within the tree and view them graphically or as an alignment
- save a plain text representation of the tree
There are 2 interactions for this family. More...
We determine these interactions using iPfam, which considers the interactions between residues in three-dimensional protein structures and maps those interactions back to Pfam families. You can find more information about the iPfam algorithm in the journal article that accompanies the website.
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 SNN_linker domain has been found. There are 1 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.
