RL J. Exp. Bot. 63:4527-4538(2012).
CC -!- FUNCTION: May be involved in membrane trafficking (By similarity).
CC Required for cell expansion, especially in root cortex, probably by
CC counteracting the action of ethylene in promoting cells radial
CC expansion (PubMed:7867930, PubMed:8275864). Involved in female organ
CC development (PubMed:14675453). Antagonistically interacts with ethylene
CC signaling to regulate plant responses to Pi starvation
CC (PubMed:22615140). {ECO:0000250|UniProtKB:K7VLR4,
CC ECO:0000269|PubMed:14675453, ECO:0000269|PubMed:22615140,
CC ECO:0000269|PubMed:7867930, ECO:0000269|PubMed:8275864}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q6IMT0}. Golgi
CC apparatus {ECO:0000250|UniProtKB:K7VLR4}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=1;
CC Comment=Additional isoforms seem to exist. {ECO:0000305};
CC Name=1;
CC IsoId=Q6IMT1-1; Sequence=Displayed;
CC -!- TISSUE SPECIFICITY: Highest levels in leaves, also expressed in leaves,
CC flowers, and siliques, and, to a lower extent, in roots and stems.
CC {ECO:0000269|PubMed:22615140}.
CC -!- DEVELOPMENTAL STAGE: In seedlings, expressed in hypocotyl and in the
CC entire cotyledon. Observed in all types of cells in the root apex, but
CC restricted to vascular tissue in the upper part of the root. Stronger
CC expression in young leaves than in old leaves. Accumulates in all
CC flower organs, including the sepal, petal, stamen, and gynoecium. In
CC the silique, high levels at both ends but weak in the middle.
CC {ECO:0000269|PubMed:22615140}.
CC -!- DISRUPTION PHENOTYPE: Dwarf plants; smaller aerial organs and wider
CC roots because of abnormal diffuse cell growth. Abnormal cell expansion
CC that is greatest in the root cortex cell layer and is independent of
CC the root growth rate, and that leads to a shift in the orientation of
CC expansion (PubMed:7867930, PubMed:8275864). Sterility due to female
CC organ anomalies (PubMed:8275864, PubMed:14675453). Enhanced responses
CC to Pi starvation (PubMed:22615140). {ECO:0000269|PubMed:14675453,
CC ECO:0000269|PubMed:22615140, ECO:0000269|PubMed:7867930,
CC ECO:0000269|PubMed:8275864}.
CC -!- MISCELLANEOUS: The sequence shown here is derived from an
CC EMBL/GenBank/DDBJ third party annotation (TPA) entry.
CC -!- SIMILARITY: Belongs to the SABRE family. {ECO:0000305}.
