Seminalplasmin: a protein with many biological properties.

Seminalplasmin, the major basic protein of bull seminal plasma, is a secretory protein of the seminal vesicles.

From the experimental results of three independent methods: (1) indirect immunofluorescence employing monospecific anti-seminalplasmin-IgGs, (2) cell-free translation of poly(A)+ RNA from seminal vesicle and testicular tissue, as well as (3) Northern analysis of poly(A)+ RNA of the latter tissues with a synthetic seminalplasmin-specific antisense DNA probe, it is concluded that the biosynthesis...

Microcalorimetric investigation of the interaction of calmodulin with seminalplasmin and myosin light chain kinase.

Flow microcalorimetric titrations of calmodulin with seminalplasmin at 25 degrees C revealed that the high affinity one-to-one complex in the presence of Ca2+ (Comte, M., Malnoe, A., and Cox, J. A. (1986) Biochem. J. 240, 567-573) is entirely enthalpy-driven (delta H0 = -50 kJ.mol-1; delta S0 = O J.K-1.mol-1; delta Cp0 = O J.K-1.mol-1) and is not influenced by the proton or Mg2+ concentration. ...

Biological and organoleptic properties of milk protein as affected by dilution with non-esential nitrogen sources

Seminalplasmin: recent evolution of another member of the neuropeptide Y gene family.

Seminalplasmin, the major basic protein of bull semen, an important regulator of calcium transport in bovine sperm and a positive modulator of the zona pellucida-induced acrosome reaction, is shown to be a recently created member of the neuropeptide Y gene family. Sequence analysis of the bovine peptide YY-pancreatic polypeptide gene cluster reveals an unexpected and extensive homology between ...

A Combination Method of Centrality Measures and Biological Properties to Improve Detection of Protein Complexes in Weighted PPI Networks

Introduction: In protein-protein interaction networks (PPINs), a complex is a group of proteins that allows a biological process to take place. The correct identification of complexes can help better understanding of the function of cells used for therapeutic purposes, such as drug discoveries. One of the common methods for identifying complexes in the PPINs is clustering, but this study aimed ...
