CC -!- FUNCTION: Transcription factor that binds to 5'-TTGAATTGA-3' elements
CC in the promoter region of target genes. Functions as a repressor of the
CC ecmB gene. Regulates the differentiation of prestalk cells during
CC development. {ECO:0000269|PubMed:10393118, ECO:0000269|PubMed:11254360,
CC ECO:0000269|PubMed:15053873, ECO:0000269|PubMed:9200609}.
CC -!- SUBUNIT: Monomer, in the absence of tyrosine phosphorylation.
CC Homodimer, or heterodimer with another family member, when tyrosine
CC phosphorylated. {ECO:0000269|PubMed:15053873,
CC ECO:0000269|PubMed:9200609}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Cytoplasmic in growing
CC cells. Translocated into the nucleus in response to cAMP-induced
CC tyrosine phosphorylation. Nuclear at the tight mound stage and in the
CC upper, prestalk region of tipped aggregates and in cells at the tip of
CC the slug. Subject to crm1-dependent nuclear export.
CC -!- DEVELOPMENTAL STAGE: Constitutively expressed with a slight increase
CC during the tight mound stage (at protein level). Detected at very low
CC levels in growing cells and aggregates up to the loose mound stage.
CC Highly expressed in tipped aggregates and in the Mexican hat stage.
CC Expressed at lower levels in early and late culminants and in fruiting
CC bodies. {ECO:0000269|PubMed:9200609, ECO:0000269|PubMed:9670017}.
CC -!- PTM: Tyrosine phosphorylated in response to cAMP. Not tyrosine
CC phosphorylated in growing cells. Tyrosine phosphorylation is first
CC detected at the tight mound stage, continues throughout the slug stage
CC and early culmination, and starts to decrease at mid-culmination.
CC Barely detectable in fruiting bodies. {ECO:0000269|PubMed:9670017}.
CC -!- DISRUPTION PHENOTYPE: Cells are hypersensitive to the chlorinated
CC hexaphenone DIF. They form slugs, but there is little or no stalk cell
CC differentiation. After several days of developmental arrest very small
CC spore masses appear that are supported by columns of apparently
CC undifferentiated cells. {ECO:0000269|PubMed:10393118}.
CC -!- SIMILARITY: Belongs to the transcription factor STAT family.
CC {ECO:0000305}.
