Proteomics Readjustment of the Yeast in Response to Increased Temperature and Alkaline Stress.

Yeasts cope with a wide range of environmental challenges using different adaptive mechanisms. They can prosper at extreme ambient pH and high temperatures; however, their adaptation mechanisms have not been entirely investigated. Previously, we showed the pivotal role and flexibility of the sugar and lipid composition of upon adaptation to unfavorable conditions.

"Prostate cancer proteomics" database.

A database of Prostate Cancer Proteomics has been created by using the results of a proteomic study of human prostate carcinoma and benign hyperplasia tissues, and of some human-cultured cell lines (PCP, http://ef.inbi.ras.

Proteomic analysis of human skeletal muscle (m. vastus lateralis) proteins: identification of 89 gene expression products.

Proteins from bioptates and autoptates of human skeletal muscle m. vastus lateralis were separated by O'Farrell two-dimensional gel electrophoresis (2DE). MALDI-TOF MS and MS/MS enabled identification of 89 protein spots as expression products of 55 genes.

Polymorphism of delta3,5-delta2,4-dienoyl-coenzyme A isomerase (the ECH1 gene product protein) in human striated muscle tissue.

Two polymorphic variants of the ECH1 gene product protein (delta3,5-delta2,4-dienoyl-coenzyme A isomerase) have been revealed by proteomics methods in samples of human striated muscle tissue. These variants are identical in molecular weight (29.7 kD) but different in pI values (6.

Proteomic studies of human and other vertebrate muscle proteins.

This review summarizes results of some systemic studies of muscle proteins of humans and some other vertebrates. The studies, started after introduction of two-dimensional gel electrophoresis of O'Farrell, were significantly extended during development of proteomics, a special branch of functional genomics. Special attention is paid to analysis of characteristic features of strategy for practical realization of the systemic approach during three main stages of these studies: pre-genomic, genomic (with organizational registration of proteomics), and post-genomic characterized by active use of structural genomics data.

A new protein of human atrium.

The partial amino acid sequence (23 amino acid residues) of a protein isolated from human atrium has been determined. The sequence homology shows that this protein belongs to the myosin 1 light chain family (an atrium-specific isoform).

The major protein expression profile and two-dimensional protein database of human heart.

The construction of a two-dimensional protein database of the human heart is presented. The database contains information on about 300 abundant proteins of human myocardial tissue, including approximately 40 proteins that were identified by different methods. Each protein was characterized according to several parameters, including molecular weight, isoelectric point, name, partial sequence, subcellular localization, and genetic as well as embryonic changes.
