機能
Binds to the PU-box, a purine-rich DNA sequence (5'-GAGGAA-3') that can act as a lymphoid-specific enhancer. This protein is a transcriptional activator that may be specifically involved in the differentiation or activation of macrophages or B-cells. Also binds RNA and may modulate pre-mRNA splicing. -
配列類似性
Belongs to the ETS family.
Contains 1 ETS DNA-binding domain. -

Predicted band size: 31 kDa
Observed band size: 37-42 kDa why is the actual band size different from the predicted?PU.1 is a 37-42 kDa member of the ets family of transcription factors. The molecule weight observed is consistent with what has been described in the literature (PMID: 28362429, 31586032, 28586009).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human tonsil tissue sections labeling PU.1/Spi1 with Purified ab76543 at 1:3000 dilution (0.035 µg/ml). Heat mediated antigen retrieval was performed using Heat mediated antigen retrieval using Bond™ Epitope Retrieval Solution 2 (pH 9.0) . Tissue was counterstained with Hematoxylin. Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) secondary antibody was used. PBS instead of the primary antibody was used as the negative control.
