Summary: P5-type ATPase cation transporter
Pfam includes annotations and additional family information from a range of different sources. These sources can be accessed via the tabs below.
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.
This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.
P5-type ATPase cation transporter Provide feedback
This domain family is found in eukaryotes, and is typically between 110 and 126 amino acids in length. The family is found in association with PF00122 PF00702. P-type ATPases comprise a large superfamily of proteins, present in both prokaryotes and eukaryotes, that transport inorganic cations and other substrates across cell membranes.

P-ATPases (also known as E1-E2 ATPases) ([intenz:3.6.3.-]) are found in bacteria and in a number of eukaryotic plasma membranes and organelles [ PUBMED:9419228 ]. P-ATPases function to transport a variety of different compounds, including ions and phospholipids, across a membrane using ATP hydrolysis for energy. There are many different classes of P-ATPases, which transport specific types of ion: H + , Na + , K + , Mg 2+ , Ca 2+ , Ag + and Ag 2+ , Zn 2+ , Co 2+ , Pb 2+ , Ni 2+ , Cd 2+ , Cu + and Cu 2+ . P-ATPases can be composed of one or two polypeptides, and can usually assume two main conformations called E1 and E2.
Transmembrane ATPases are membrane-bound enzyme complexes/ion transporters that use ATP hydrolysis to drive the transport of protons across a membrane. Some transmembrane ATPases also work in reverse, harnessing the energy from a proton gradient, using the flux of ions across the membrane via the ATPase proton channel to drive the synthesis of ATP.
There are several different types of transmembrane ATPases, which can differ in function (ATP hydrolysis and/or synthesis), structure (e.g., F-, V- and A-ATPases, which contain rotary motors) and in the type of ions they transport [ PUBMED:15473999 , PUBMED:15078220 ]. The different types include:
- F-ATPases (ATP synthases, F1F0-ATPases), which are found in mitochondria, chloroplasts and bacterial plasma membranes where they are the prime producers of ATP, using the proton gradient generated by oxidative phosphorylation (mitochondria) or photosynthesis (chloroplasts).
- V-ATPases (V1V0-ATPases), which are primarily found in eukaryotes and they function as proton pumps that acidify intracellular compartments and, in some cases, transport protons across the plasma membrane [ PUBMED:20450191 ]. They are also found in bacteria [ PUBMED:9741106 ].
- A-ATPases (A1A0-ATPases), which are found in Archaea and function like F-ATPases, though with respect to their structure and some inhibitor responses, A-ATPases are more closely related to the V-ATPases [ PUBMED:18937357 , PUBMED:1385979 ].
- P-ATPases (E1E2-ATPases), which are found in bacteria and in eukaryotic plasma membranes and organelles, and function to transport a variety of different ions across membranes.
- E-ATPases, which are cell-surface enzymes that hydrolyse a range of NTPs, including extracellular ATP.
These P-type ATPases from eukaryotes form a different clade, designated subfamily V [ PUBMED:9419228 ]. P-type ATPases use ATP for intracellular cation homeostasis and are required for proper lysosomal and mitochondria maintenance [ PUBMED:32973005 ], also playing a role in the maintenance of neuronal integrity [ PUBMED:27278822 ]. P-type ATPases are also involved in the uptake and/or transport of polyamines, contributing to the polyamines homeostasis within the cells [ PUBMED:19762559 ].

Alignments
We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets and the UniProtKB sequence database. More...
View options
We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

HMM logos is one way of visualising profile HMMs. Logos provide a quick overview of the properties of an HMM in a graphical form. You can see a more detailed description of HMM logos and find out how you can interpret them here. More...
Trees
This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.
Note: You can also download the data file for the tree.

Structures
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 P5-ATPase domain has been found. There are 4 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 sequence.
