GeneCards Summary for TAL1 Gene

TAL1 (T-Cell Acute Lymphocytic Leukemia 1) is a Protein Coding gene. Diseases associated with TAL1 include t-cell leukemia and cd3epsilon deficiency. Among its related pathways are Lymphocyte Signaling. GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and chromatin binding. An important paralog of this gene is LYL1.

UniProtKB/Swiss-Prot for TAL1 Gene

  • Implicated in the genesis of hemopoietic malignancies. It may play an important role in hemopoietic differentiation. Serves as a positive regulator of erythroid differentiation (By similarity).

Post-translational modifications for TAL1 Gene

  • Phosphorylated on serine residues. Phosphorylation of Ser-122 is strongly stimulated by hypoxia (By similarity).
  • Ubiquitinated; subsequent to hypoxia-dependent phosphorylation of Ser-122, ubiquitination targets the protein for rapid degradation via the ubiquitin system. This process may be characteristic for microvascular endothelial cells, since it could not be observed in large vessel endothelial cells (By similarity).
  • Modification sites at PhosphoSitePlus
  • Ubiquitination at Lys185, Lys234, and Lys241
