**作者**: Chen R, et al.

**摘要**: 利用Phospho-Ser122抗体，作者发现TAL-1的Ser122磷酸化由MAPK信号通路介导。磷酸化修饰降低了TAL-1与DNA的结合亲和力，从而抑制其转录活性，这一机制可能解释TAL-1在特定肿瘤微环境中的功能异质性。

背景信息

The TAL-1 (Phospho-Ser122) antibody is designed to detect the phosphorylation of the TAL-1 protein at serine residue 122. TAL-1 (T-cell acute lymphoblastic leukemia 1), also known as SCL (stem cell leukemia), is a basic helix-loop-helix (bHLH) transcription factor critical for hematopoiesis and endothelial development. It regulates the differentiation and proliferation of hematopoietic stem cells and is frequently implicated in T-cell acute lymphoblastic leukemia (T-ALL) due to chromosomal translocations or dysregulated expression.

Phosphorylation at Ser122 is a post-translational modification that modulates TAL-1’s transcriptional activity, stability, or interactions with cofactors. This site-specific phosphorylation may influence TAL-1’s oncogenic potential, as aberrant activation of TAL-1 disrupts normal hematopoietic cell fate, promoting leukemogenesis. The TAL-1 (Phospho-Ser122) antibody enables researchers to study the dynamic regulation of TAL-1 activity in cellular signaling pathways, such as those involving MAPK/ERK or other kinases that target this residue.

This antibody is widely used in techniques like Western blotting, immunoprecipitation, or immunofluorescence to assess TAL-1 activation status in cancer models, hematopoietic differentiation studies, or drug screening. Its specificity for the phosphorylated form helps distinguish active TAL-1 from its unmodified state, providing insights into mechanisms underlying T-ALL progression and potential therapeutic targets. Validation typically includes testing in cell lines with known TAL-1 expression and phosphorylation status to ensure reliability.
