Domain

Na-Ca exchanger/integrin-beta4 (IPR003644)

Short name: Calx_beta

Domain relationships

None.

Description

The calx-beta motif is present as a tandem repeat in the cytoplasmic domains of Calx Na-Ca exchangers, which are used to expel calcium from cells. This motif overlaps domains used for calcium binding and regulation. The calx-beta motif is also present in the cytoplasmic tail of mammalian integrin-beta4, which mediates the bi-directional transfer of signals across the plasma membrane, as well as in some cyanobacterial proteins. This motif contains a series of beta-strands and turns that form a self-contained beta-sheet [PMID: 9294196, PMID: 10390612].
