Protein: Xyloglucan endotransglucosylase/hydrolase protein 4 (At-XTH4) (XTH-4) (EC 2.4.1.207) (Q39099)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Catalyzes xyloglucan endohydrolysis (XEH) and/or endotransglycosylation (XET). Cleaves and religates xyloglucan polymers, an essential constituent of the primary cell wall, and thereby participates in cell wall construction of growing tissues.
Subcellular location: Secreted, cell wall {ECO:0000305}. Secreted, extracellular space, apoplast {ECO:0000269|PubMed:15593128}.
