1. Estudos estruturais e termodinâmicos de centrinas BeCen1 e BeCen3 do fungo Blastocladiella emersonii / Structural and Thermodynamics Studies of Blastocladiella Emersonii Centrins
Centrinas são proteínas componentes essenciais nos centro organizadores de microtubulos em diversos organismos. Pertencem à família das proteínas EF-Hand ligantes de cálcio e podem ser divididas em duas subfamílias: uma definida pela centrina da alga Chlamydomonas reinhardtii CrCenp, associada a funções contráteis, e a outra pela centrina da levedu

2. Centrin4p, a Novel Mammalian Centrin Specifically Expressed in Ciliated Cells
Centriole assembly plays an important role in centrosome duplication during the cell cycle and is a prerequisite for cilia formation during the differentiation of ciliated cells. In spite of numerous investigations, the molecular machinery that governs centriole/basal body formation remains enigmatic. Recent reports suggest that the ubiquitously expresse

3. Cloning, Localization, and Axonemal Function of Tetrahymena Centrin
Centrin, an EF hand Ca2+ binding protein, has been cloned in Tetrahymena thermophila. It is a 167 amino acid protein of 19.4 kDa with a unique N-terminal region, coded by a single gene containing an 85-base pair intron. It has > 80% homology to other centrins and high homology to Tetrahymena EF hand proteins calmodulin, TCBP23, and TCBP25. Specific cellular

4. Characterization of multigene families in the micronuclear genome of Paramecium tetraurelia reveals a germline specific sequence in an intron of a centrin gene.
In Paramecium, as in other ciliates, the transcriptionally active macronucleus is derived from the germline micronucleus by programmed DNA rearrangements, which include the precise excision of thousands of germline-specific sequences (internal eliminated sequences, IESs). We report the characterization of micronuclear versions of genes encoding Paramecium se
