Western blot analysis of extracts from A431 (lane 2(20μg), A431 (lane 3(40μg), using Phospho-STAT5(Tyr694) Antibody. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature. -

Background

Function
STAT5 comprises STAT5A and STAT5B, transcription factors that regulate hematopoietic cell proliferation, differentiation, and apoptosis[1]. Mechanistically, STAT5 tyrosine phosphorylation in peripheral T cells is driven by cytokine receptor signaling rather than the T-cell receptor complex[2]. This cytokine-linked pathway supports immune regulation, lymphocyte development, and cell survival programs[3]. In disease contexts, STAT5B deficiency is associated with growth failure, immunodeficiency, and severe pulmonary disease[4]. Compared with STAT5A, STAT5B shows dominant activity in effector and regulatory T-cell responses, with paralog dose explaining much functional specificity[5]. In BCR/ABL leukemia models, STAT5B, but not STAT5A, serves as the major STAT5 isoform driving leukemogenesis[6]. For experimental applications, AC-4-130 directly binds STAT5 and disrupts activation, dimerization, nuclear translocation, and STAT5-dependent transcription in AML models[7]. Pimozide also decreases survival of chronic myelogenous leukemia cells resistant to kinase inhibitors[8].

Isoforms & Post-Translational Modification
P42229 has 2 isomers: P42229-1: 90647 Da (predicted); P42229-2: 86949 Da (predicted).
Tyrosine phosphorylated in response to KITLG/SCF, IL2, IL3, IL7, IL15, CSF2/GMCSF, GH1, PRL, EPO and THPO (By similarity). Activated KIT promotes phosphorylation on tyrosine residues and subsequent translocation to the nucleus (PubMed:21135090). Tyrosine phosphorylated in response to constitutively activated FGFR1, FGFR2, FGFR3 and FGFR4 (By similarity). Tyrosine phosphorylation is required for DNA-binding activity and dimerization. Serine phosphorylation is also required for maximal transcriptional activity (By similarity). Tyrosine phosphorylated in response to signaling via activated FLT3; wild-type FLT3 results in much weaker phosphorylation than constitutively activated mutant FLT3 (PubMed:14504097). Alternatively, can be phosphorylated by JAK2 at Tyr-694 (PubMed:12529425);ISGylated -
Subunit
Forms a homodimer or a heterodimer with a related family member. Binds NR3C1 (By similarity). Interacts with NCOA1 and SOCS7 (PubMed:12954634). Interacts with ERBB4 (PubMed:15534001). Interacts with EBF4 (PubMed:35939714). Interacts with CD69 (By similarity)
