Target

  • Function

    Carries out a dual function: signal transduction and activation of transcription. Mediates cellular responses to the cytokine KITLG/SCF and other growth factors. Binds to the GAS element and activates PRL-induced transcription.
  • Involvement in disease

    Growth hormone insensitivity with immunodeficiency
  • Sequence similarities

    Belongs to the transcription factor STAT family.
    Contains 1 SH2 domain.
  • Post-translational
    modifications

    Tyrosine phosphorylated in response to signaling via activated KIT, resulting in translocation to the nucleus. Tyrosine phosphorylated in response to signaling via activated FLT3; wild-type FLT3 results in much weaker phosphorylation than constitutively activated mutant FLT3. Alternatively, can be phosphorylated by JAK2. Phosphorylation at Tyr-699 by PTK6 or HCK leads to an increase of its transcriptional activity. Dephosphorylation on tyrosine residues by PTPN2 negatively regulates prolactin signaling pathway.
  • Cellular localization

    Cytoplasm. Nucleus. Translocated into the nucleus in response to phosphorylation.
