      • signal transducer and activator of transcription 5B
      • transcription factor STAT5B
      Background InformationThe STAT proteins (signal transducer and activator of transcription) comprise a family of transcription factors. STATs are activated through tyrosine phosphorylation, mainly by JAK kinases, which results in their dimerization, nuclear translocation and regulation of gene expression. STAT5 activity is induced by numerous cytokines and growth factors. While STAT5A and STAT5B share 96% amino acid homology, the two isoforms have distinct physiological functions. Phosphorylation of tyrosine 694/699 is a key marker of STAT5A/B activation.

      Entrez Gene Number
      Entrez Gene SummaryThe protein encoded by this gene is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein mediates the signal transduction triggered by various cell ligands, such as IL2, IL4, CSF1, and different growth hormones. It has been shown to be involved in diverse biological processes, such as TCR signaling, apoptosis, adult mammary gland development, and sexual dimorphism of liver gene expression. This gene was found to fuse to retinoic acid receptor-alpha (RARA) gene in a small subset of acute promyelocytic leukemias (APLL). The dysregulation of the signaling pathways mediated by this protein may be the cause of the APLL. [provided by RefSeq]

      UniProt Number
      UniProt SummaryFUNCTION: Carries out a dual function: signal transduction and activation of transcription. Binds to the GAS element and activates PRL-induced transcription.

      SUBUNIT: Forms a homodimer or a heterodimer with a related family member. Binds NR3C1 By similarity. Interacts with NCOA1 and SOCS7.

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

      PTM: Tyrosine phosphorylated in response to IL-2, IL-3, IL-7, IL-15, GM-CSF, growth hormone, prolactin, erythropoietin and thrombopoietin. Tyrosine phosphorylation is required for DNA-binding activity and dimerization. Serine phosphorylation is also required for maximal transcriptional activity By similarity.

      SIMILARITY: Belongs to the transcription factor STAT family.

      Contains 1 SH2 domain.
