Description

IPR005782 is a P-type ATPase, subfamily IIA, SERCA-type.

<p>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.</p> <p>P-ATPases (also known as E1-E2 ATPases) ([ec:3.6.3.-]) are found in bacteria and in a number of eukaryotic plasma membranes and organelles [[cite:PUB00009616]]. 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⁺, Mg²⁺, Ca²⁺, Ag⁺and Ag²⁺, Zn²⁺, Co²⁺, Pb²⁺, Ni²⁺, Cd²⁺, Cu⁺and Cu²⁺. P-ATPases can be composed of one or two polypeptides, and can usually assume two main conformations called E1 and E2.</p> <p>This entry represent the P-type ATPase responsible for translocating calcium ions across the endoplasmic reticulum membrane of eukaryotes [[cite:PUB00017632]], and is of particular importance in the sarcoplasmic reticulum of skeletal and cardiac muscle in vertebrates [[cite:PUB00017633]]. These pumps transfer Ca2+ from the cytoplasm to the lumen of the endoplasmic reticulum. In humans and mice, at least, there are multiple isoforms of the SERCA pump with overlapping but not redundant functions. Defects in SERCA isoforms are associated with diseases in humans [[cite:PUB00017634]]. The calcium P-type ATPases have been characterised as Type IIA based on a phylogenetic analysis which distinguishes this group from the Type IIB PMCA calcium pump [[cite:PUB00009616]] described in [interpro:IPR006408]. A separate analysis divides Type IIA into sub-types, SERCA and PMR1 [[cite:PUB00009622]] the latter of which is described in [interpro:IPR006413].</p>
