Protein
Casparian strip membrane protein 4
Organism
Populus trichocarpa
Function
Regulates membrane-cell wall junctions and localized cell wall deposition. Required for establishment of the Casparian strip membrane domain (CSD) and the subsequent formation of Casparian strips, a cell wall modification of the root endodermis that determines an apoplastic barrier between the intraorganismal apoplasm and the extraorganismal apoplasm and prevents lateral diffusion (By similarity).
Similarity
Belongs to the Casparian strip membrane proteins (CASP) family.
