The button next to the article title ("Edit Wikipedia article") takes you to the edit page for the article directly within Wikipedia.

Does Pfam agree with the content of the Wikipedia entry ?
Pfam has chosen to link families to Wikipedia articles. In some case we have created or edited these articles but in many other cases we have not made any direct contribution to the content of the article. The Wikipedia community does monitor edits to try to ensure that (a) the quality of article annotation increases, and (b) vandalism is very quickly dealt with. However, we would like to emphasise that Pfam does not curate the Wikipedia entries and we cannot guarantee the accuracy of the information on the Wikipedia page.
Editing Wikipedia articles
Before you edit for the first time
Wikipedia is a free, online encyclopedia. Although anyone can edit or contribute to an article, Wikipedia has some strong editing guidelines and policies, which promote the Wikipedia standard of style and etiquette. Your edits and contributions are more likely to be accepted (and remain) if they are in accordance with this policy.

How your contribution will be recorded
Anyone can edit a Wikipedia entry. You can do this either as a new user or you can register with Wikipedia and log on. When you click on the "Edit Wikipedia article" button, your browser will direct you to the edit page for this entry in Wikipedia. If you are a registered user and currently logged in, your changes will be recorded under your Wikipedia user name. However, if you are not a registered user or are not logged on, your changes will be logged under your computer's IP address. This has two main implications. Firstly, as a registered Wikipedia user your edits are more likely seen as valuable contribution (although all edits are open to community scrutiny regardless). Secondly, if you edit under an IP address you may be sharing this IP address with other users. If your IP address has previously been blocked (due to being flagged as a source of 'vandalism') your edits will also be blocked. You can find more information on this and creating a user account at Wikipedia.
If you have problems editing a particular page, contact us at email@example.com and we will try to help.
The community annotation is a new facility of the Pfam web site. If you have problems editing or experience problems with these pages please contact us.
Sorting nexin, N-terminal domain Provide feedback
These proteins bins to the cytoplasmic domain of plasma membrane receptors. and are involved in endocytic protein trafficking. The N-terminal domain appears to be specific to sorting nexins 1 and 2.
This tab holds annotation information from the InterPro database.
InterPro entry IPR005329
Sorting nexins (SNXs) are hydrophilic molecules that are localized in the cytoplasm and have the potential for membrane association either through their lipid-binding PX domains (INTERPRO) or through protein-protein interactions with membrane-associated protein complexes [PUBMED:12461558]. Indeed, several of the SNXs require several targeting motifs for their appropriate cellular localization. In almost every case studied, mammalian SNXs can be shown to have a role in protein sorting, with the most commonly used experimental model being plasma-membrane receptor endocytosis and sorting through the endosomal pathway. However, it is equally probable that SNXs sort vesicles that are not derived from the plasma membrane, and have a function in the accurate targeting of these vesicles and their cargo.
The N-terminal domain appears to be specific to sorting nexins 1 and 2. SNX1 is both membrane-associated and cytosolic, where it probably exists as a tetramer in large protein complexes and may hetero-oligomerize with SNX2.

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:
