Biological context of Taf4


Associations of Taf4 with chemical compounds

  • In both Drosophila cells and yeast, TAF110 specifically interacts with the glutamine-rich activation domains of Sp1 [1].
  • The PI3K_68D cDNA encodes a protein of 210 kDa, which lacks sequences implicated in linking p110 PI 3-kinases to p85 adaptor proteins, but contains an amino-terminal proline-rich sequence, which could bind to SH3 domains, and a carboxy-terminal C2 domain [7].

Other interactions of Taf4

  • Coimmunoprecipitation studies with anti-dTBP, anti-dTFIIA-L, and anti-TAF antibodies indicated a tight association of the endogenous dTFIIA and dTFIID [8].
  • Strikingly, the structural interaction is tissue specific: nht did not interact with dTAF12 and dTAF4 did not interact with rye in a bacterial co-expression assay [9].
  • This means that the interactions observed in vitro between Bcd and TAFII60 or TAFII110 aid transcriptional activation but are dispensable for normal development [10].
