功能: function:Major component of the Descemet's membrane (basement membrane) of corneal endothelial cells.,miscellaneous:Four consecutive Gly-Pro-Pro triplets are present at the C-terminus of the triple-helical region. These may provide the high thermal stability of this region.,PTM:Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.,similarity:Contains 1 C1q domain.,subunit:May form homotrimers, or heterotrimers in association with alpha 2(VIII) type collagens.,
组织表达: Expressed primarily in the subendothelium of large blood vessels. Also expressed in arterioles and venules in muscle, heart, kidney, spleen, umbilical cord, liver and lung and is also found in connective tissue layers around hair follicles, around nerve bundles in muscle, in the dura of the optic nerve, in cornea and sclera, and in the perichondrium of cartilaginous tissues. In the kidney, expressed in mesangial cells, glomerular endothelial cells, and tubular epithelial cells. Also expressed in mast cells, and in astrocytes during the repair process. Expressed in Descemet's membrane. Specifically expressed in peritoneal fibroblasts and mesothelial cells.
