Differential translation of Dazap1 transcripts during spermatogenesis.

ABSTRACT: Deleted in AZoospermia Associated Protein 1 (DAZAP1) is a ubiquitous hnRNP protein that has been implicated in RNA transcription, splicing, and translation. It is highly expressed in testes, predominantly in late stage spermatocytes and post-meiotic spermatids. Dazap1 deficiency in mice results in growth retardation and spermatogenic arrest. The gene produces two major transcripts of 2.4 and 1.8 kb, designated Dazap1-L and Dazap1-S, respectively. Results of our previous RNA in situ hybridization and immunostaining suggested translational regulation of the Dazap1 transcripts during spermatogenesis. The main objectives of the study were to determine the origin of the two Dazap1 transcripts and to investigate whether they were similarly translated. Our Northern and 3' RACE analyses showed tha
