前胶原c -蛋白酶增强剂(PCPE)是一种糖蛋白,可通过骨形态发生蛋白-1 (BMP-1)促进I型前胶原c -前肽的酶切。人类PCPE基因(PCOLCE)先前被定位于7q22,这是子宫平滑肌瘤中经常被破坏的区域,而大鼠PCPE基因的破坏导致大鼠成纤维细胞不依赖锚定生长和失去接触抑制。在这里,我们描述了Pcolce和小鼠PCPE基因(Pcolce)的整个内含子/外显子组织,并分析了pcolcerna在各种人类成人和胎儿组织中的表达以及pcolcerna在小鼠发育的不同阶段的表达。pcolce和pcolceare分别为6.0和6.5 kb的小基因,具有保守的内含子/外显子结构,包括9个外显子。这两个基因之间的显著差异来自于在pcolce的上游和下游插入多个基因序列。在小鼠发育过程中,PCPE mRNA的时间表达与BMP-1和I型前胶原的时间表达不同,这与PCPE在增强c蛋白酶活性之外可能具有的其他功能一致。与平滑肌瘤的可能作用一致,pcolce1在子宫中表达水平相对较高。
The procollagen C-proteinase enhancer (PCPE) is a glycoprotein that potentiates enzymatic cleavage of the type I procollagen C-propeptide by bone morphogenetic protein-1 (BMP-1). The human PCPE gene (PCOLCE) was previously mapped to 7q22, an area frequently disrupted in uterine leiomyomata, while disruption of the rat PCPE gene leads to anchorage-independent growth and loss of contact inhibition in rat fibroblasts. Here we describe the entire intron/exon organizations ofPCOLCEand the mouse PCPE gene (Pcolce) and analyze expression ofPCOLCERNA in various human adult and fetal tissues and ofPcolceRNA at various stages of mouse development.PCOLCEandPcolceare shown to be small genes 6.0 and 6.5 kb, respectively, with a conserved intron/exon structure comprising 9 exons. A notable difference between the two genes derives from insertion of multipleAlusequences immediately upstream and downstream and withinPCOLCE.Temporal expression of PCPE mRNA is shown to differ from that of BMP-1 and type I procollagen during mouse development, consistent with possible additional functions for PCPE beyond enhancement of C-proteinase activity. Consistent with a possible role in leiomyomata,PCOLCEis shown to be expressed at relatively high levels in uterus.
