- Expression of betaig-h3 by human bronchial smooth muscle cells: localization To the extracellular matrix and nucleusP C Billings
Department of Anatomy and Histology, School of Dental Medicine, University of Pennsylvania, Philadelphia, Pennsylvania 19104 6002, USA
Am J Respir Cell Mol Biol 22:352-9. 2000..The presence of this protein in nuclei suggests that it may have regulatory functions in addition to its role as a structural component of lung ECM...
- Extracellular matrix and nuclear localization of beta ig-h3 in human bladder smooth muscle and fibroblast cellsP C Billings
Department of Anatomy and Histology, University of Pennsylvania, School of Dental Medicine, Philadelphia, Pennsylvania 19104, USA
J Cell Biochem 79:261-73. 2000..We propose that although this protein is a structural component of bladder ECM, its nuclear localization suggests that it has other regulatory and/or structural functions...
