GFI1b Antibody (720344) in ICC/IF
For immunofluorescence analysis, THP-1 cells were fixed and permeabilized for detection of endogenous GFI1b using Anti- GFI1b Rabbit Polyclonal Antibody (Product # 720344, 5 µg/mL) and labeled with Goat anti-Rabbit IgG (Heavy Chain) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Panel a) shows representative cells that were stained for detection and localization of GFI1b protein (green), Panel b) is stained for nuclei (blue) using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938).

Target Information
GFI1b (zinc finger protein GFI-1b) is an essential proto-oncogenic transcriptional regulator necessary for development and differentiation of erythroid and megakaryocytic lineages. It is also a component of a RCOR-GFI-KDM1A-HDAC complex that suppresses, via histone deacetylase (HDAC) recruitment, a number of genes implicated in multilineage blood cell development and controls hematopoietic differentiation. GFI1b also acts as a transcriptional repressor or activator depending on both promoter and cell type context; represses promoter activity of SOCS1 and SOCS3 and thus, may regulate cytokine signaling pathways. It also cooperates with GATA1 to repress target gene transcription, such as the apoptosis regulator BCL2L1; GFI1B silencing in leukemic cell lines markedly increase apoptosis rate. Mutations affecting the gene are associated with Bleeding disorder, platelet-type 17 (BDPLT17).
