Prohibitin probably acts as a holdase/unfoldase for the stabilization of newly synthesized mitochondrial proteins. Component of a prohibitin multimeric complex in mitochondrial membranes. Mostly expressed in proliferative tissues, including vasculature, shoot and root apical tissues. Accumulates in dry seeds. Observed in all organs primordia and meristems. In cotyledons, hypocotyls and differentiating leaves, present in stomatal meristemoid cells, guard mother cells and trichomes. Within the anthers, transiently expressed in the proximity of the sporogenous tissue. Accumulates in embryos at globular stages, except in suspensor cell. In root elongation zones, mostly present in epidermal cells, particularly in trichoblasts. Transcripts levels decrease upon imbibition but remains stable at the protein level. Belongs to the prohibitin family.
