ab183032 staining TBR1 in Human cerebral organoid tissue sections by Immunohistochemistry (PFA perfusion fixed frozen sections). Tissue samples were fixed by perfusion with paraformaldehyde, permeabilized with 0.1% Triton X, blocked with 5% serum for 1 hour at room temperature and antigen retrieval was by heat mediation in Dako target retrieval. The sample was incubated with primary antibody (1 : 300 dilution) at 4oC for 12 hours. An Alexa Fluor® 488 conjugate goat polyclonal (1/200) was used as the secondary antibody.

Supplementary information

TBR1 also known as T-Box Brain 1 is a transcription factor important for neuronal development. It weighs about 74 kDa. This protein is strongly expressed in the cerebral cortex during prenatal stages where it plays a role in regulating gene expression. TBR1 influences the differentiation and migration of cortical neurons which is critical for proper brain development.
Biological function summary

TBR1 influences neuronal differentiation through its function as a transcription factor. It binds to specific DNA sequences to regulate gene expression required for neuronal identity and function. TBR1 is part of a larger transcriptional complex that includes other proteins like CASK and TBR2 contributing to the maturation of cortical neurons. TBR1's role in these processes highlights its significance in neuronal circuit formation in the cerebral cortex.

Pathways

TBR1 is involved in the Wnt signaling and the reelin pathway which are both essential for normal brain development. In the Wnt signaling pathway TBR1 interacts with proteins such as LEF1 to influence cell fate decision and pattern formation. In the reelin pathway TBR1 work along with proteins like Reelin itself to regulate neuronal positioning promoting the correct layering of the cortex.

TBR1 has strong associations with autism spectrum disorders and intellectual disabilities. Mutations in TBR1 disrupt its role in gene regulation during brain development leading to the aforementioned neurological conditions. TBR1 also interacts with FOXP2 a protein involved in language and speech linking it further to communication-related aspects of these disorders.

Target data

Transcriptional repressor involved in multiple aspects of cortical development, including neuronal migration, laminar and areal identity, and axonal projection (PubMed : 25232744, PubMed : 30250039). As transcriptional repressor of FEZF2, it blocks the formation of the corticospinal (CS) tract from layer 6 projection neurons, thereby restricting the origin of CS axons specifically to layer 5 neurons (By similarity).
