Protein attributes

Sequence length	743 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Transcriptional repressor involved in developmental processes. Probably plays a role in limb pattern formation. Ref.1
Subcellular location	Nucleus Potential.
Tissue specificity	Widely expressed.
Involvement in disease	Defects in TBX3 are the cause of ulnar-mammary syndrome (UMS) [MIM:181450]. UMS is characterized by ulnar ray defects, obesity, hypogenitalism, delayed puberty, hypoplasia of nipples and apocrine glands. Ref.3

Alternative products

This entry describes 4 isoforms produced by alternative splicing. [Align] [Select]

Isoform II (identifier: O15119-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Note: Contains an interrupted T-box domain.

Isoform I (identifier: O15119-2)

The sequence of this isoform differs from the canonical sequence as follows:
     221-240: Missing.

Isoform III (identifier: O15119-3)

The sequence of this isoform differs from the canonical sequence as follows:
     490-615: Missing.
     661-677: Missing.

Note: Contains an interrupted T-box domain.

Isoform IV (identifier: O15119-4)

The sequence of this isoform is not available.

Note: May be produced by joining exon 1 to exon 7 thereby eliminating the T-box.
