GTF2B Antibodies

AND GTF2B ELISA kits, GTF2B Proteins

Many biological assays use antibodies to detect GTF2B, such as Western Blot (WB), ELISA, Flow Cytometry, Immunocytochemistry (IHC). These antibodies can be polyclonal or monoclonal, and react with GTF2B in Human, Mouse, Rat, and many other animal samples. Boster Bio use mainly mouse and rabbit to develop GTF2B antibodies...

We validate the specificity of these antibodies to GTF2B by testing them on tissues known to express GTF2B positively and negatively. Browse below to find the GTF2B antibody that suites your experiment. We have 5 of these antibodies and many publications and validation images.

If you cannot find antibodies that fit your needs, contact us for making custom antibodies. We have a full suite of custom antibody services covering from research to diagnostic and therapeutic applications.

GTF2B Overview

Facts about Transcription initiation factor IIB.

GTF2B 3D structure. Source: alphafold

Transcription initiation factor IIB (GTF2B)

General transcription factor that plays a role in transcription initiation by RNA polymerase II (Pol II). Involved in the pre-initiation complex (PIC) formation and Pol II recruitment at promoter DNA (PubMed:1876184, PubMed:1946368, PubMed:1517211, PubMed:3818643, PubMed:3029109, PubMed:8413225, PubMed:8515820, PubMed:8516311, PubMed:8516312, PubMed:7601352, PubMed:9420329, PubMed:12931194, PubMed:27193682).

Together with the TATA box-bound TBP forms the center initiation complex and provides a bridge between TBP and the Pol II-TFIIF complex (PubMed:8504927, PubMed:8413225, PubMed:8515820, PubMed:8516311, PubMed:8516312). Published from the PIC early following the onset of transcription during the initiation and elongation transition and reassociates with TBP through the next transcription cycle (PubMed:7601352).

Location:	1p22.2
Sequence:	1; NC_000001.11 (88852633..88891944, complement)

Tissue Specificity

Expressed in the inner cell mass forming the embryoblast (PubMed:24441171). Not detected in cells from the outer thin layer trophoblast (at protein level) (PubMed:24441171).

Subcellular Localizations

Nucleus. Chromosome. Non-acetylated form colocalizes with DNA in the G0/1, S and G2 phases of the cell cycle, but not during mitosis (PubMed:24441171). Acetylated form colocalizes at transcriptionally silent mitotic chromatids during mitosis at metaphase, anaphase, and telophase phases of the cell cycle (PubMed:24441171).
