Protein

Putative expansin-A17

Gene

EXPA17

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Causes loosening and extension of plant cell walls by disrupting non-covalent bonding between cellulose microfibrils and matrix glucans. No enzymatic activity has been found (By similarity). Target of the transcriptional activator LBD18. Regulated by LBD18 to promote lateral root formation (PubMed:23872272).By similarity1 Publication

Miscellaneous

Plants silencing EXPA17 exhibit reduced number of emerged lateral roots. Plants over-expressing EXPA17 show increased density of emerged lateral roots.1 Publication
