We have studied the control of transcription of the testicular angiotensin converting enzyme (ACEt) in normal and transgenic mice. Northern analyses, including a developmental curve and separated germ cells, for ACEt mRNA suggest predominantly post-m

Outer dense fibers (ODF) or accessory fibers are filamentous structures of the sperm tail of many eumetozoan organisms endowed with internal fecundation. The bovine and porcine cDNA of an outer dense fiber protein was cloned, sequenced and compared t

Acrosin is a serine proteinase located in the acrosome of the sperm in a zymogen form, proacrosin. As deduced from the cDNA sequences of human, boar, and mouse proacrosin, the enzyme is synthesized as a preproenzyme, preproacrosin, which contains a h

During elongation and condensation of the spermatid nucleus, histones are replaced by spermatid-specific transition proteins (TNP). TNP1 is well characterized at the cDNA and at the genomic level and was found to be highly conserved during mammalian

The mitochondrial capsule selenoprotein (MCS) is a selenium-containing polypeptide. It is one of three proteins that are important for the maintenance and stabilization of the crescent structure of the sperm mitochondria. In this paper, we report the

The proacrosin gene is transcribed in diploid spermatogenic cells and translated in haploid round spermatids. In order to evaluate sequences which are involved in proacrosin gene transcription, DNA-protein interactions were analyzed in 1.2 kb of the

Proacrosin, the zymogen form of the serine protease acrosin, is located within the acrosomal vesicle of mammalian spermatozoa and has been suggested to be involved in the fertilization process. In mouse and rat, expression of the proacrosin gene star

We have isolated the gene for transition protein 2 (TNP2) from a human cosmid clone that contains the genes for protamines 1 and 2. A nucleotide sequence of 1776 bp that comprises 268 bp of the 5′-noncoding region, 400 bp of exon 1, 849 bp of an in

Protamine 2 (PRM2) is a low molecular weight arginine-rich protein which is present in haploid spermatogenic cells of human and mouse. Although the bull PRM2 gene is translated and transcribed at low levels, the protein could not be detected. The gen

The nucleotide sequence and exon-intron organization of the proacrosin gene was determined. It consists of 6 exons and 5 introns of which one is located in the 5' untranslated region. The transcription initiation site was determined at position 471 (
