General description

Tbr1 gene is a member of a conserved family of genes that share a common DNA-binding domain, the T-box. T-box genes encode transcription factors involved in the regulation of developmental processes. Tbr1, a putative transcription factor known to be expressed in post-mitotic neurons, has been found highly expressed in glutamatergic early-born cortical neurons. A similar protein has been disrupted in mice and shown to be critical for early cortical development, and causes loss of projection neurons in the olfactory bulbs and olfactory cortex. The C-terminal region the Tbr1 derived protein was found to be necessary and sufficient for association with the guanylate kinase domain of calcium/calmodulin-dependent serine protein kinase.


Epitope: This antibody recognizes Tbr1 near the N-terminus.

KLH-conjugated linear peptide corresponding to mouse Tbr1 near the N-terminus.


Anti-Tbr1 Antibody detects level of Tbr1 & has been published & validated for use in IH(P).

Immunohistochemistry Analysis: 1:400 dilution from a previous lot detected Tbr1 in mouse cerebellum tissue.
