TBR1
protein-coding gene in the species Homo sapiens

T-box, brain, 1 is a transcription factor protein important in vertebrate embryo development. It is encoded by the TBR1 gene. This gene is also known by several other names: T-Brain 1, TBR-1, TES-56, and MGC141978. TBR1 is a member of the TBR1 subfamily of T-box family transcription factors, which share a common DNA-binding domain. Other members of the TBR1 subfamily include EOMES and TBX21. TBR1 is involved in the differentiation and migration of neurons and is required for normal brain development. TBR1 interacts with various genes and proteins in order to regulate cortical development, specifically within layer VI of the developing six-layered human cortex. Studies show that TBR1 may play a role in major neurological diseases such as Alzheimer's disease (AD), Parkinson's disease (PD) and autism spectrum disorder (ASD).
Discovery
TBR1 was identified in 1995 by the Nina Ireland Laboratory of Developmental Neurobiology Center at the University of California, San Francisco. The gene, initially named TES-56, was found to be largely expressed in the telencephalic vesicles of the developing forebrain of mice.
“TBR1” enters the record as protein-coding gene in the species Homo sapiens. Crown Archives preserves that source wording while asking what TBR1, protein-coding and gene can confirm, complicate or overturn.
Why this record matters
“TBR1” is worth following because a concise public description often conceals a longer documentary argument. Here, TBR1, protein-coding and gene provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jan 19, 2026. The linked authority identifier is Q18035619. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1995.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.

- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “TBR1”, its source revision and the description used here.
- Expand the search: follow TBR1 primary sources, TBR1 archive and TBR1 research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
