Highly expressed in lymph node, jejunum, pancreas, stomach, trachea, testis, uterus and placenta; moderately expressed in brain, colon, lung, prostate, spinal cord, salivary gland and vascular smooth-muscle cells and very weakly expressed in heart, liver, kidney, bone marrow, spleen, thymus, skeletal muscle, adrenal gland and peripheral leukocytes. Expression in heart was higher in the right ventricle and atrium than in the left ventricle and atrium.
Secreted, extracellular space, extracellular matrix. Cytoplasm. Found in the extracellular matrix component of blood vessel walls and in the cytoplasm of cultured human aortic smooth muscle.
