KRAB-containing zinc-finger repressor proteins
Raul Urrutia
Genome Biology , 2003, DOI: 10.1186/gb-2003-4-10-231
Abstract: Zinc-finger proteins containing the Krüppel-associated box (KRAB-containing proteins) were discovered in 1991 by Bellefroid et al. [1]. They make up approximately one third (290) of the 799 different zinc-finger proteins present in the human genome, and as a result, this group of proteins is the largest single family of transcriptional regulators in mammals. Many genes encoding KRAB-containing proteins are arranged in clusters, but others occur individually throughout the genome. The best characterized cluster is on 19q, containing 148 genes (51% of the family) within a region close to 19q13 [2]; other clusters are in centromeric and telomeric regions of other chromosomes. In particular, members of the family containing SCAN domains (see below) are clustered on 3p21-22, 6p21-22, 16p13.3, and 17p12-13. Non-clustered genes encoding KRAB-containing proteins are scattered over the other chromosomes, with about half on autosomes and half on sex chromosomes. Although the expression of genes of other clustered families, such as homeobox genes, is coregulated, it remains to be determined whether a comparable mechanism operates for genes encoding KRAB-containing proteins, and more studies are needed to show how chromosome organization influences the expression patterns of this family.As shown in Figure 1, KRAB-containing proteins are characterized by the presence of a DNA-binding domain made up of between 4 and over 30 zinc-finger motifs and a KRAB domain. The KRAB domain, located near the amino terminus of the protein, consists of one or both of the KRAB A box and the KRAB B box (see below). Other domains, such as the SCAN domain, are found in a small subset of members of the family [2,3] (Table 1). The two boxes of the KRAB domain are always encoded by individual exons separated by introns of variable sizes. This exon-intron composition allows the generation of different products by alternative splicing. In fact, zinc-finger proteins that contain only a KRAB A domain, for
Los eslabonamientos y la historia económica de Colombia
Urrutia,Miguel;
Desarrollo y Sociedad , 2008,
Abstract: the paper analyzes albert hirschman′s theory of linkages in economic development in his writings, and the possible influence of his colombia experience in the development of this idea. the theory is then applied to explain colombia's economic history in the nineteenth and twentieth century.
Hacia una política en tránsito: Ficción en el cine chileno (2008-2010)
Urrutia,Carolina;
Aisthesis , 2010, DOI: 10.4067/S0718-71812010000100003
Abstract: cinema is political in the sense that film camera never takes a neutral position and it always manages to establish a dialog with its social and cultural environment. in fact, although chilean contemporary fiction dissociates itself from any explicit ideological discourse due to its primary focus on intimacy and everyday life, its alienated representation of life turns into a purely political feeling of unease and uncertainty.
Script, un modelo cognitivo del lenguaje.: Estudio experimental a partir de tres grupos etáreos
Urrutia,Mabel;
Revista signos , 2004, DOI: 10.4067/S0718-09342004005500005
Abstract: this article gives account of an experimental research that consists of outlining the structure and functioning of possible forms of organization of human knowledge, from a script of a visit to the doctor's. the corpus consists of oral reports transcribed that give an account of the experiences of the subjects of study when visiting the doctor's. the subjects are divided in three age groups: 10 young people, 10 adults and 10 elder people of michaihue, an area in san pedro de la paz, in concepcion. the results obtained contribute to the information about the way in which these scripts are stored in the human memory, the different linguistics tendencies among the number of events and peripheral ways, according to their age; and the way in which these mental constructs, scripts, leave an imprint in future actions of human experience, as it has been observed in this experience with users of chilean public health service.

Hacia una política en tránsito: Ficción en el cine chileno (2008-2010) Politics in Transit: Chilean Cinema (2008-2010)
Carolina Urrutia
Aisthesis , 2010,
Abstract: El cine es político desde una cámara que nunca adopta una posición neutra y que siempre logra establecer un vínculo con su entorno social y cultural. En la ficción chilena contemporánea, asistimos a un cine donde prima lo íntimo y lo cotidiano, y a pesar de que el registro se desmarca de cualquier discurso explícitamente ideológico, su representación extra ada y alienada se inscribe en una sensación de malestar e incertidumbre que deviene política. Cinema is political in the sense that film camera never takes a neutral position and it always manages to establish a dialog with its social and cultural environment. In fact, although Chilean contemporary fiction dissociates itself from any explicit ideological discourse due to its primary focus on intimacy and everyday life, its alienated representation of life turns into a purely political feeling of unease and uncertainty.
