CC -!- FUNCTION: Transcription elongation factor that enhances the
CC transcription elongation by RNA polymerase II (RNAPII) (By similarity).
CC Plays an important role in regulating embryo apical and basal
CC patterning during early embryogenesis, partly through negative
CC regulation of the transcription factors PHABULOSA and PHAVOLUTA.
CC {ECO:0000250|UniProtKB:Q7KZ85}.
CC -!- SUBUNIT: Interacts (via N-terminus) with IWS1.
CC {ECO:0000269|PubMed:20139304}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=1;
CC Name=1;
CC IsoId=A8MS85-1; Sequence=Displayed;
CC -!- TISSUE SPECIFICITY: Expressed in shoot apical meristem, leaf primordia,
CC vasculature of young leaves, inflorescence meristem, floral meristem,
CC young floral organs, developing ovules and anthers.
CC {ECO:0000269|PubMed:21948524}.
CC -!- DEVELOPMENTAL STAGE: During embryo development, expressed throughout
CC embryos at the globular, heart, torpedo and bent-cotyledon stages.
CC {ECO:0000269|PubMed:21948524}.
CC -!- DISRUPTION PHENOTYPE: Embryonic lethality leading to aborted seed
CC development. {ECO:0000269|PubMed:21948524}.
CC -!- MISCELLANEOUS: [Isoform 1]: A number of isoforms are produced.
CC According to EST sequences. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the SPT6 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAC27151.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
