Carbonic anhydrase 3 (CA3) is a member of a gene family encoding proteins which catalyse the hydration of CO2 to generate protons and bicarbonate ions for cellular ion transport and pH homeostasis. In mouse embryos CA3 is expressed at high levels in notochord and skeletal muscle and here we demonstrate that this pattern of expression is the same in the developing human embryo. To investigate mechanisms controlling CA3 transcription, we have isolated and compared 2.8kb of sequence flanking exon 1 from the mouse and human genes. Several segments of high sequence identity >80% have been identified, the longest segments of which represent a proximal promoter region and a putative enhancer element. We have shown previously that in cultured cells the human 2.8kb promoter region imposes high level myogenic specific transcription of a reporter gene. However, we now show that while this promoter region directed muscle-specific expression in transgenic mouse embryos this was subject to position effects.
