Demonstration of acrosin in mouse spermatozoa.
Gelatinolytic activity of whole mouse spermatozoa was demonstrated by the gelatin film test. The presence of a trypsin-like protease (acrosin) in acidic extracts of mouse spermatozoa was shown by an electrophoretic method to separate the enzyme from a putative inhibitor.
متن کاملDetection and localization of antigens on the surface of mouse spermatozoa. Antigen synthesis in the epididymis.
Spermatozoa achieve functional maturity during their transit through the epididymis and this maturation process is accompanied by changes in the composition and proteins of their surface. The addition of secretory products from the epididymis to the plasma membranes of the spermatozoa is considered to be a prerequisite for the acquisition by the spermatozoa of the capacities for forward motilit...
متن کاملThe nitric oxide synthase of mouse spermatozoa.
Nitric oxide synthase (NOS) was evidenced in mature mouse spermatozoa by means of biochemical techniques and Western blot. During 120 min of incubation, 10(7) spermatozoa synthesized 7 +/- 2 pmol of L-[14C]citrulline. Besides, L-citrulline formation depended on the incubation time and on the concentration of L-arginine present in the incubation medium. Different concentrations of N(G)-nitro-L-a...
متن کاملp95, the major phosphotyrosine-containing protein in mouse spermatozoa, is a hexokinase with unique properties.
Mouse sperm contain a major phosphotyrosine-containing protein of M(r) 95,000 (nonreducing conditions) which has been implicated as a sperm membrane receptor for the egg zona pellucida glycoprotein, ZP3 (Leyton, L., and Saling, P. (1989) Cell 57, 1123-1130; Leyton, L., LeGuen, P., Bunch, D., and Saling, P. (1992) Proc. Natl. Acad. Sci. U. S. A. 89, 11692-11695). This protein was purified and su...
متن کاملCerebral protein synthesis in a genetic mouse model of phenylketonuria.
Local rates of cerebral protein synthesis (lCPS(leu)) were measured with the quantitative autoradiographic [1-(14)C]leucine method in a genetic mouse model (Pah(enu2)) of phenylketonuria. As in the human disease, Pah(enu2) mice have a mutation in the gene for phenylalanine hydroxylase. We compared adult homozygous (HMZ) and heterozygous (HTZ) Pah(enu2) mice with the background strain (BTBR). Ar...
