CC -!- FUNCTION: DNA-binding protein that regulates the transcription of
CC several genes and is involved in heart development and limb pattern
CC formation. May bind to the core DNA motif of promoters.
CC {ECO:0000250|UniProtKB:Q99593}.
CC -!- SUBUNIT: Monomer. Homodimer (via the T-box); binds DNA as homodimer.
CC {ECO:0000250|UniProtKB:Q99593}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q99593,
CC ECO:0000255|PROSITE-ProRule:PRU00201}. Cytoplasm
CC {ECO:0000250|UniProtKB:Q99593}. Note=Shuttles between the cytoplasm and
CC the nucleus. {ECO:0000250|UniProtKB:Q99593}.
CC -!- DEVELOPMENTAL STAGE: In late neurulae (stage 19), expression seen
CC within the eye anlagen, with higher levels dorsally. At early tail bud
CC stage (stage 25), expressed in each developing eye and in the heart
CC primordia, located ventrally. In stage 26 embryos, the Tbx5-expressing
CC cells of the heart primordia are seen to converge at the ventral
CC midline, while expression also seen in two bilateral groups of cells
CC continuous with and extending dorsally from the heart primordia.
CC Expression in the dorsal region of the eye found to be maintained until
CC early tadpole stages (stage 40), although expression becomes greatly
CC restricted between stages 33 and 40. At stage 31/32, strong expression
CC detected in the posterior region of the heart tube. After looping of
CC the heart, a higher level of expression detected in the ventricle than
CC in the atrium. {ECO:0000269|PubMed:16477648}.
CC -!- DOMAIN: The T-Box domain binds to double-stranded DNA.
CC {ECO:0000250|UniProtKB:Q99593}.
