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

General annotation (Comments)

Subunit structure	Forms homodimer or heterodimer with other members of the family.
Tissue specificity	Isoform 2 is expressed in colon, breast, prostate, pancreas and kidney tumor cell lines. Isoform 2 is expressed at high levels in kidney, prostate, brain, small intestine and pancreas, at moderate levels in placenta and colon, at low levels in lung, liver and heart, and at very low levels in spleen, thymus, peripheral mononuclear blood cells, testis and ovary. Ref.2
Developmental stage	Isoform 2 is expressed at lower levels in fetal brain and kidney than in adult brain and kidney. Ref.2
Sequence similarities	Belongs to the TPD52 family.
