CC -!- FUNCTION: Transcription activator involved in the control of organ size
CC (PubMed:24486766). Acts as an auxin-dependent regulator for cell
CC expansion during organ size control (PubMed:24486766). Binds to the
CC promoter of PHI-1, a gene that regulates cell expansion, and positively
CC regulates its expression (PubMed:24486766). Cooperatively functions in
CC a transactivating complex with DLT to enhance the transcription of the
CC SMOS1 target PHI-1, and to regulate plant organ size (PubMed:28069545).
CC Interaction between SMOS1 and DLT is a crosstalk point for auxin and
CC brassinosteroid (BR) signaling (PubMed:28069545). Acts as positive
CC regulator of BR signaling (PubMed:28100707). Cooperatively functions in
CC a transactivating complex with BZR1 to enhance the transcription of BR
CC biosynthetic genes (PubMed:28100707). {ECO:0000269|PubMed:24486766,
CC ECO:0000269|PubMed:28069545, ECO:0000269|PubMed:28100707}.
CC -!- SUBUNIT: Interacts (via C-terminus) with DLT (PubMed:28069545).
CC Interacts with NSP2 and SHR1 (PubMed:28069545). Interacts with BZR1 and
CC GSK2 (PubMed:28100707). {ECO:0000269|PubMed:28069545,
CC ECO:0000269|PubMed:28100707}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00366,
CC ECO:0000269|PubMed:24486766, ECO:0000269|PubMed:28100707}. Cytoplasm
CC {ECO:0000269|PubMed:28069545, ECO:0000269|PubMed:28100707}.
CC Note=Localizes mostly in the nucleus. {ECO:0000269|PubMed:24486766,
CC ECO:0000269|PubMed:28100707}.
CC -!- TISSUE SPECIFICITY: Expressed in the apical region of leaf blades,
CC young leaf sheaths, a broad area below the shoot apical mersistem (SAM)
CC and near the tip of primordial leaves (PubMed:24486766). In developing
CC roots, expressed at the tip of seminal roots and lateral root tips
CC (PubMed:24486766). Expressed in developing nodes and basal region of
CC internodes (PubMed:24486766). In flowers, expressed in lemma, palea and
CC anthers (PubMed:24486766). {ECO:0000269|PubMed:24486766}.
CC -!- INDUCTION: Induced by auxin (PubMed:24486766). Induced by
CC brassinosteroid (at protein level), but repressed by brassinosteroid at
CC mRNA level probably via a negative regulatory feedback loop
CC (PubMed:28100707). {ECO:0000269|PubMed:24486766,
CC ECO:0000269|PubMed:28100707}.
CC -!- PTM: Phosproylated by GSK2 (PubMed:28100707). Phosphorylation of SMOS1
CC leads to its degradation by an unknown mechanism (PubMed:28100707).
CC {ECO:0000269|PubMed:28100707}.
CC -!- DISRUPTION PHENOTYPE: Reduced size of various organs due to decreased
CC cell size, increased cell number, and abnormal cell arrangement and
CC microtubule orientation (PubMed:24486766). Brassinosteroid (BR) loss-
CC of-function phenotype with semidwarf plants, reduced length of
CC internodes, erect leaves, up-regulation of BR biosynthetic genes and
CC decreased sensitivity to BR (PubMed:28100707).
CC {ECO:0000269|PubMed:24486766, ECO:0000269|PubMed:28100707}.
CC -!- SIMILARITY: Belongs to the AP2/ERF transcription factor family. AP2
CC subfamily. {ECO:0000305}.
