Multiple sequence alignment of DGCR6 protein sequences. Shown are the predicted amino acid sequences of the human hDGCR6 andhDGCR6L genes and their comparison to the mouse homolog,mDgcr6 (Mus musculus; Lindsay et al. 1997), chicken homolog, cDgcr6 (Gallus gallus; GenBank accession no. AF048985), and the Drosophila melanogaster gonadal protein, dgdl (Schulz and Butler 1989).
