Protein attributes

Sequence length	318 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Tissue specificity	Highly expressed in placenta, small intestine, spleen, kidney, thymus, liver, salivary gland and testes. Weakly expressed in breast, skeletal muscle and colon. Highly expressed in breast cancer upon interaction between tumor cells and stromal cells in vitro. Expressed in blood mononuclear cells from patients with systemic lupus erythematosus (SLE). Ref.1 Ref.7
Induction	Up-regulated in breast carcinomas. Ref.1
Sequence caution	The sequence CAD38599.2 differs from that shown. Reason: Miscellaneous discrepancy. Intron retention. Authors have ignored retained intron when translating.
