function:May play a role in hematopoietic differentiation or inflammation.,induction:Up-regulated by LPS, in some cancer cells such as promyelocytic leukemia cells (HL-60) or myelomonocytic leukemia cells (U-937).,similarity:Belongs to the cystatin family.,subcellular location:May be targeted through the Golgi via the secretory pathway.,tissue specificity:Expressed in heart, placenta, lung, liver, skeletal muscle and pancreas. Not expressed in brain. Barely expressed in tumor cell lines except for breast adenocarcinoma MCF-7 cells and U251 cells.,
Secreted . May be targeted through the Golgi via the secretory pathway. .
Expressed in heart, placenta, lung, liver, skeletal muscle and pancreas (PubMed:12535658). Not expressed in brain (PubMed:12535658). Expressed in epididymis, kidney, testis, spinal cord, and thymus with a strong expression in epididymis and kidney and a weak expression in the spinal cord and thymus (PubMed:20565543).
