Protein attributes

Sequence length	751 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Segment polarity protein. Functions together with arm to transduce the Wingless (Wg) signal in embryos and in developing adult tissues. Acts as a transcriptional activator, but in the absence of arm, it binds to gro and acts as a transcriptional repressor of wg-responsive genes.
Subunit structure	Binds to the beta-catenin homolog arm or to gro.
Subcellular location	Nucleus.
Miscellaneous	Flies lacking pan exhibit a segment polarity phenotype and altered expression of the wg target genes en and Ubx.
Sequence similarities	Belongs to the TCF/LEF family. Contains 1 HMG box DNA-binding domain.

Alternative products

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

Isoform A (identifier: P91943-3)

Also known as: C; D; E; F; G;

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.

Isoform H (identifier: P91943-4)

The sequence of this isoform differs from the canonical sequence as follows:
     313-364: ELSREEQSKY...RKKDRSTTDS → ALGREEQAKY...KRKRKQDTND

Notes: No experimental confirmation available.

Isoform I (identifier: P91943-5)

The sequence of this isoform differs from the canonical sequence as follows:
     313-364: ELSREEQSKY...RKKDRSTTDS → ALGREEQAKY...KRKRKQDTND
     390-414: RKKKCIRYMEALNGNGPAEDGSCFD → YVLPLFLFTMLYILLQMDLQDSRKN
     415-751: Missing.

Notes: No experimental confirmation available.

Isoform J (identifier: Q8IMA8-1)

The sequence of this isoform can be found in the external entry Q8IMA8-1.
Isoforms of the same protein are often annotated in two different entries if their sequences differ significantly.

Notes: No experimental confirmation available.
