Sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (IPR030327)

Short name: SERCA2

Family relationships

Description

SERCA2 belongs to the IIA subfamily of P-type ATPases, whose members are Ca2+ ATPases that catalyse the hydrolysis of ATP coupled with the transport of calcium across the membrane. SERCA2 is a specialised Ca2+ pump, known as SERCA pump, which is localised in sarcoplasmic reticulum and endoplasmic reticulum [PMID: 17286271].

Mutations in the SERCA2 gene cause Darier disease, which is characterised by loss of adhesion between suprabasal epidermal keratinocytes (acantholysis) and abnormal keratinization (dyskeratosis) [PMID: 20423818]. There are several alternatively spliced SERCA2 isoforms in humans that are involved in maintaining normal heart function [PMID: 19962989].
