Research Backgrounds


Carries out a dual function: signal transduction and activation of transcription. Involved in IL4/interleukin-4- and IL3/interleukin-3-mediated signaling.


Tyrosine phosphorylated on Tyr-641 following stimulation by IL4/interleukin-4. Tyrosine phosphorylated following stimulation by IL3/interleukin-3 (By similarity). Dephosphorylation on tyrosine residues by PTPN2 negatively regulates the IL4/interleukin-4 mediated signaling.

Mono-ADP-ribosylated by PARP14.

Subcellular Location:

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

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Subunit Structure:

Forms a homodimer or a heterodimer with a related family member (By similarity). Interacts with NCOA1 via its C-terminal LXXLL motif.


Belongs to the transcription factor STAT family.

Figure 5 PARP14 deficiency activates the STAT1 pathway but blocks the STAT6 pathway in mice 7 days post-SCI. (A) Representative images and quantitative analysis showing p-STAT1 (Try701)+/Iba1+ immunofluorescence staining. Lv-shPARP14 injection further promoted SCI-induced STAT1 pathway activation. White arrows indicate p-STAT1 (Try701)+ (green, FITC-labeled)/Iba1+ (red, Cy3-labeled, microglia marker) cells. (B) Representative images and quantitative analysis showing p-STAT6 (Tyr641)+/Iba1+ immunofluorescence staining. Lv-shPARP14 injection inhibited SCI-induced STAT6 pathway activation. White arrows indicated p-STAT6 (Tyr641)+ (green, FITC-labeled)/Iba1+ (red, Cy3-labeled) cells. Scale bars: 50 µm. (C) Relative protein levels of p-STAT1 (Try701), and p-STAT6 (Tyr641) in each group were detected by western blot analysis. p-STAT1 (Try701) expression was increased by Lv-shPARP14 injection, but p-STAT6 (Tyr641) expression was decreased by PARP14 silencing. Values are shown as mean ± SD (n = 6). **P < 0.01 (one-way analysis of variance followed by Tukey’s post hoc test). Images were taken from the gray matter ventral horn at the injury site. Spinal cord tissues from the injury site were used for western blot detection.
