Disease relevance of STAT5A

  • Moreover, 4ICD and STAT5A colocalize within nuclei of heregulin beta 1 (HRG)-stimulated cells and both proteins bind to the endogenous beta-casein promoter in T47D breast cancer cells [1].
  • Human immunodeficiency virus type 1 infection inhibits granulocyte-macrophage colony-stimulating factor-induced activation of STAT5A in human monocyte-derived macrophages [2].
  • We conclude that HIV-1 inhibits GM-CSF activation of STAT5A without affecting expression of the known components of the signaling pathway [2].
  • Activation of the Jak2-Stat5 signaling pathway in Nb2 lymphoma cells by an anti-apoptotic agent, aurintricarboxylic acid [3].
  • We review these various defects with an emphasis on the GH-activated JAK2-STAT5 pathway, since this pathway is essential for normal body growth and there has been recent progress in our understanding of the perturbations that occur in uremia [4].
  • We also found that persistently phosphorylated Stat5 in primary cells from patients with myeloid leukemias has a cytoplasmic localization [5].
 

High impact information on STAT5A

 

Chemical compound and disease context of STAT5A

 

Biological context of STAT5A

 

Anatomical context of STAT5A

  • To determine the functional significance of 4ICD nuclear translocation in a physiologically relevant system, we have demonstrated that cotransfection of ERBB4 and STAT5A in a human breast cancer cell line stimulates beta-casein promoter activity [1].
  • In BCR-Abl transformed K562 cells, STAT5A and 5B are constitutively phosphorylated on tyrosine and are transcriptionally active [17].
  • Granulocyte-macrophage colony-stimulating factor preferentially activates the 94-kD STAT5A and an 80-kD STAT5A isoform in human peripheral blood monocytes [18].
  • Macrophages lost their ability to express the 80-kD STAT5A protein, but retained their ability to activate STAT5A [18].
  • We have reported previously that expression of STAT5B, but not STAT5A, could enhance the transforming potential of v-src and induces cell cycle progression and motility in fibroblasts [19].
 

Associations of STAT5A with chemical compounds

 

Physical interactions of STAT5A

 

Enzymatic interactions of STAT5A

  • MGF-Stat5 can be phosphorylated and activated in its DNA binding activity by Jak2 [27].
  • Ectopically expressed BTK kinase domain was capable of tyrosine-phosphorylating STAT5A both in vitro and in vivo [15].
  • Because Stat5 phosphorylation following cytokine stimulation is generally mediated by Jaks, the lack of Jak activation after TSLP treatment suggested the possibility that tyrosine-phosphorylated Stat5 may be nonfunctional [28].
  • On the other hand, the 92-kDa STAT5 was tyrosine phosphorylated within 1 min of GM-CSF treatment and this was maintained for at least 30 min [29].
  • STAT5 was a major component of this DNA-binding complex, and STAT5 was tyrosine phosphorylated in response to TPO [30].
 

Regulatory relationships of STAT5A

 

Other interactions of STAT5A

  • Expression of the dominant-negative form of STAT5B, but not of STAT5A, significantly decreased both p21(waf) expression and the fraction of cells in G1 [34].
  • Tyrosine phosphorylation and activation of STAT5, STAT3, and Janus kinases by interleukins 2 and 15 [35].
  • The present study further analyzed the underlying mechanisms and demonstrated that EPO-mediated STAT5 transactivation in the erythroid AS-E2 cell line was enhanced 6-fold by PGE2 (10 microM), without affecting the STAT5 tyrosine phosphorylation or STAT5-DNA binding [22].
  • Detailed analysis indicated that STAT5A specificity is more similar to that of STAT6 than that of STAT1, as expected from the evolutionary relationships [36].
  • Suppressor of cytokine signaling 7 inhibits prolactin, growth hormone, and leptin signaling by interacting with STAT5 or STAT3 and attenuating their nuclear translocation [37].
