Brn3b Antibody

Brn3b (Brain-Specific Homeobox/POU Domain Protein 3B) or POU4F2 (POU Class 4 Homeobox 2) is a DNA-binding transcriptional regulator and coregulator that recognizes and binds to the consensus octamer binding site 5-AT[A/T]A[T/A]T[A/T]A-3 in promoter of target genes. Brn3b plays a fundamental role in the gene regulatory network essential for retinal ganglion cell (RGC) differentiation. It cooperates with the transcription factor ISL1 to achieve RGC fate specification in the developing retina. And plays a role in RGC axon formation and guidance by regulating gene expression of specific target genes. Brn3b plays a role in TNFSF11-mediated terminal osteoclast differentiation. It binds chromatin at promoter region of target genes. It acts either as a transcriptional activator or repressor. It plays a role in the regulation of breast cancer cell growth by promoting transcription activation as well as repression of specific target genes. It is involved in tumor breast progression and invasion. Brn3b also plays a role either as a transcriptional coactivator or corepressor. Anti-Brn3b Antibody is useful for researchers interested in breast cancer research, transcription factor activity, and DNA binding. Anti-Brn3b Antibody has been tested in WB, IHC, and IF. Expect a band at ~43kDa in western blot using appropriate lysates. Positive controls used: Rat pup PND2-6 – minimal cortex brain lysate in WB, Mouse testis in IHC, Post-natal rat pup (PND1) heterogeneous brain cells in IF.
