Expression -- Description ? help Back to Top
Source	Description
Uniprot	DEVELOPMENTAL STAGE: Expressed during seed development (PubMed:18567831). Exclusively expressed in the endosperm of developing seeds (PubMed:18849529). {ECO:0000269\|PubMed:18567831, ECO:0000269\|PubMed:18849529}.
Uniprot	TISSUE SPECIFICITY: Siliques. Not detected in roots, rosette leaves or flowers. Expressed in endosperm cells. {ECO:0000269\|PubMed:12679534, ECO:0000269\|PubMed:18567831}.

Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor that controls embryo growth (PubMed:18567831, PubMed:18849529, PubMed:23318634). Regulates endosperm breakdown and embryonic epidermal development. Regulates the expression of SBT2.4/ALE1 (PubMed:18849529, PubMed:23318634). Involved in embryonic cuticle formation upstream of SBT2.4/ALE1 (PubMed:23318634). Does not seem to be a general regulator of endosperm patterning. May control specific signaling pathways that coordinate embryo invasion and breakdown of surrounding endosperm tissues (PubMed:18849529). Required for the production the embryo sheath, an extracuticular endosperm-derived structure at the surface of the embryo. Acts upstream of KRS (PubMed:28696222). {ECO:0000269\|PubMed:18567831, ECO:0000269\|PubMed:18849529, ECO:0000269\|PubMed:23318634, ECO:0000269\|PubMed:28696222}.
