功能
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. -
疾病相关
Growth hormone insensitivity with immunodeficiency -
序列相似性
Belongs to the transcription factor STAT family.
Contains 1 SH2 domain. -
翻译后修饰
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. -

ab178941 was shown to react with STAT5B in wild-type HAP1 cells in Western blot with loss of signal observed in a STAT5B knockout cell line. Wild-type HAP1 and STAT5B knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab178941 overnight at 4°C at a 1/1000 dilution. Blots were incubated with secondary antibodies at 0.2µg/mL before imaging.

Chromatin was prepared from T-47D (starved overnight) treated with Prolactin(10nM 30min) and T-47D(starved overnight) non-treated cells according to the Abcam Dual-X-ChIP protocol*. Cells were fixed with 1.5 mM EGS for 30mins and then formaldehyde for 10min.
The ChIP was performed with 25 μg of chromatin, 5 μg of ab178941 (red), or 5 μg of rabbit normal IgG ab172730 (gray) and 20 μL of Protein A/G sepharose beads. The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).
