Protein attributes

Sequence length	1426 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Involved in signal transduction through the Wnt pathway. Promotes beta-catenin's transcriptional activity By similarity. Ref.4
Subunit structure	Binds to beta-catenin (CTNNB1), PYGO1 and PYGO2.
Subcellular location	Nucleus By similarity.
Tissue specificity	Detected at low levels in thymus, prostate, testis, ovary and small intestine, and at lower levels in spleen, colon and blood.
Post-translational modification	Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.5 Ref.6 Ref.7 Ref.8 Ref.9
Involvement in disease	A chromosomal aberration involving BCL9 is found in a patient with precusor B-cell acute lymphoblastic leukemia (ALL). Translocation t(1;14)(q21;q32). This translocation leaves the coding region intact, but may have pathogenic effects due to alterations in the expression level of BCL9. Several cases of translocations within the 3'-UTR of BCL9 have been found in B-cell malignancies.
Sequence similarities	Belongs to the BCL9 family.
Caution	It is uncertain whether Met-1 or Met-27 is the initiator.
Sequence caution	The sequence CAA73942.1 differs from that shown. Reason: Frameshift at position 1391.
