Powering down the Pfam website
On October 5th, we will start redirecting the traffic from Pfam (pfam.xfam.org) to InterPro (www.ebi.ac.uk/interpro). The Pfam website will be available at legacy.pfam.xfam.org until January 2023, when it will be decommissioned. You can read more about the sunset period in our blog post.

Protein: SRP09_HUMAN (P49458)


This is the summary of UniProt entry SRP09_HUMAN (P49458).

Description: Signal recognition particle 9 kDa protein
Source organism: Homo sapiens (Human) (NCBI taxonomy ID 9606)
Length: 86 amino acids
Reference Proteome: ✓

Please note: when we start each new Pfam data release, we take a copy of the UniProt sequence database. This snapshot of UniProt forms the basis of the overview that you see here. It is important to note that, although some UniProt entries may be removed after a Pfam release, these entries will not be removed from Pfam until the next Pfam data release.

Sequence information

This is the amino acid sequence of the UniProt sequence database entry with the accession P49458. This sequence is stored in the Pfam database and updated with each new Pfam release, but this means that the sequence we store may differ from that stored by UniProt.

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 SIFTS project, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between Pfam domains, this UniProt entry and a corresponding three dimensional structure.
