UniProt annotation for SUB_ARATH » Protein STRUBBELIG
FUNCTION: Regulates the expression of transcription factors that define the cell fates. Acts in a non-cell-autonomous fashion, functions in a radial inside-out signaling process, and mediates cell morphogenesis and cell fate across clonally distinct cell layers in floral primordia, developing ovules, and root meristems. Seems to be required for the regulation of cell shape and the orientation of the mitotic division plane. Involved in root hair specification, in the formation of the outer integument and the shape of organs such as carpels and petals and is necessary for the shape and height of the stem. Non-functional SUB proteins are retained in the endoplasmic reticulum and degraded by endoplasmic reticulum-associated degradation (ERAD).

ENZYME REGULATION: Regulated at the post-transcriptional level.

SUBUNIT: Interacts (via intra-cellular domain) with AN; this interaction is not required for correct subcellular localization and recycling of SUB.

TISSUE SPECIFICITY: Expressed in leaves, stems, inflorescences, flower buds and developing root epidermis.

DEVELOPMENTAL STAGE: Required for epidermal patterning during postembryonic root development, but not involved in hypocotyl development.

DOMAIN: The protein kinase domain is catalytically inactive, but nevertheless important for SUB function.

MISCELLANEOUS: Cannot be functionally replaced by the SRF1 to SRF8 proteins.

MISCELLANEOUS: The sub/scm phenotype is sensitive to ecotype and is greatly reduced in cv. Columbia background.

MISCELLANEOUS: Phosphorylation of Thr-486, Thr-494 or Ser-656 is not required for SUB function.
