Calx_betaDomains in Na-Ca exchangers and integrin-beta4
|SMART accession number:||SM00237|
|Description:||Domain in Na-Ca exchangers and integrin subunit beta4 (and some cyanobacterial proteins)|
|Interpro abstract (IPR003644):|
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 [(PUBMED:9294196), (PUBMED:10390612)].
