We isolated the complete deleted-in-azoospermia-like-1 (DAZL1) gene of the old world monkey Macaca fascicularis (tentatively designated as MafaDAZL1) and compared its sequence structure to that of the other DAZL1 genes isolated so far. In addition to the homologous RNA recognition motif (RRM domain), we only identified a high conservation of the Mafa-DAZL1 coding region to the mammalian DAZL1 genes (i.e. mouse: Dazl1; and human: DAZL1) and to that of Xenopus (xdazl). Only in the primates, Macaca fascicularis and human, sequences and lengths of the 5' and 3' untranslated DAZL1 gene structures (UTRs) displayed a similar conservation as their coding regions (i.e. 91-94%). Both belong to the primate class of old world monkeys evolutionarily separated 36-55 million years ago (1). The strong conservation of the complete DAZL1 gene structure in both primate species suggests a similar control and maturation pathway of DAZL1 transcripts in the germ line of old world monkeys and also indicates a homologous function of the DAZL1 RNA-binding protein in this primate class.
