Solute Carrier Family 43, Member 3 (SLC43A3)

A screen for genes differentially regulated in a model of kidney development identified the novel gene embryonic epithelia gene 1 (EEG1). EEG1 exists as two transcripts of 2.4 and 3.5 kb that are most highly expressed at embryonic day 7 and later in the fetal liver, lung, placenta, and kidney. The EEG1 gene is composed of 14 exons spanning a 20-kb region at human chromosome 11p12 and the syntenic region of mouse chromosome 2. Six EEG1 exons have previously been assigned to a longer isoform of eosinophil major basic protein termed proteoglycan 2. Another gene distantly related to EEG1, POV1/PB39, is located 88 kb upstream from the EEG1 gene on chromosome 11. Temporal expression of 65 members of the solute carrier (SLC)-class of transport proteins was followed during kidney development using DNA arrays.
