Domain

Casparian strip membrane protein domain (IPR006702)

Short name: CASP_dom

Overlapping homologous superfamilies

None.

Domain relationships

None.

Description

This domain is found mainly in plant proteins known as Casparian strip membrane proteins (CASPs). CASPs are four-membrane-span proteins that mediate the deposition of Casparian strips in the endodermis by recruiting the lignin polymerization machinery. Interestingly, the CASP first extracellular loop was found conserved in euphyllophytes but absent in plants lacking Casparian strips [PMID: 21593871, PMID: 24920445].
