| abstractText | We have identified two novel human genes encoding proteins with a high level of sequence identity to two previously characterized RNA-binding proteins, alphaCP-1 and alphaCP-2. Both of these novel genes, alphaCP-3 and alphaCP-4, are predicted to encode proteins with triplicated KH domains. The number and organization of the KH domains, their sequences, and the sequences of the contiguous regions are conserved among all four alphaCP proteins. The common evolutionary origin of these proteins is substantiated by conservation of exon-intron organization in the corresponding genes. The map positions of alphaCP-1 and alphaCP-2 (previously reported) and those of alphaCP-3 and alphaCP-4 (present report) reveal that the four alphaCP loci are dispersed in the human genome; alphaCP-3 and alphaCP-4 mapped to 21q22.3 and 3p21, and the respective mouse orthologues mapped to syntenic regions of the mouse genome, 10B5 and 9F1-F2, respectively. Two additional loci in the human genome were identified as alphaCP-2 processed pseudogenes (PCBP2P1, 21q22.3, and PCBP2P2, 8q21-q22). Although the overall levels of alphaCP-3 and alphaCP-4 mRNAs are substantially lower than those of alphaCP-1 and alphaCP-2, transcripts of alphaCP-3 and alphaCP-4 were found in all mouse tissues tested. These data establish a new subfamily of genes predicted to encode closely related KH-containing RNA-binding proteins with potential functions in posttranscriptional controls.
